"Unique, memorable, fractured and obtuse. A visually compelling world surrounding fascinating ideas. Crave the avant garde? Experience it."


“FRACT OSC is one of the best original games released on Steam in a long time. It is abundantly clear that it has been created by a team that shares an equal passion for both music and games, and its unique concept and gorgeous, vibrant world deserve to be explored by as many people possible. If you’re in ownership of functioning eyes and ears, then you owe it to yourself to play this game.”
9/10 – Game Revolution

“When you succeed and the final piece of the puzzle slots into place, your reward isn’t a text backslap, achievement popup or skill point, but a drop. Beats and bass crash in as the record you’ve been piecing together reaches a crescendo. It’s like having Boards Of Canada noodling away behind you as you work on the world’s hardest jigsaw puzzle and both of you having two very different eureka moments at the same time.”
8/10 – Edge

“If [HP Lovecraft] had been a coder rather than a writer and had been into Autechre and Aphex Twin rather than gross racism, I can't help thinking this is the sort of game he would have come up with . . . Like all great interactive experiences, this is a game that happens almost entirely in your own head, an ongoing internal narrative that pushes and pulls between questions of how and why that are never given an easy resolution.”
8/10 – Eurogamer

Static washes out your vision, slowly fading away to reveal large and impossible geometric objects reaching up and out as far as you can see. Dead machinery jutting out from pastel colored ground and rock. You don’t know how exactly you got here nor how any of these strange constructs were built. Your legs carry you across the land, poking your head into enclosed buildings that might as well be giant tombs. At last, you come across an object that emits a strange hum. You touch it and the hum changes pitch slightly in reaction. You move it around and it changes tempo and pitch respective to where it was before. You don’t know what is going on but you sure as hell are nodding your head.

FRACT OSC is like a Fantasia for the dance-minded music fans. IDisneylandM, if we were to give it a genre tag in our music player. Much like the Aggro-crag, every area on the map is color coded according to the theme of the sounds you’ll expect to hear. Pink acts as your bubbling leads, blue as your bass and green as the airy pads. Each instrument has its own dedicated area in the mountain area FRACT takes place in. The leads come from such towering heights, the pads sit in the middle and the bass rumbles on from down below. There are other, smaller details which show themselves to musician and non-musician alike which key you in to each place’s role in the overall scheme of what is going on.

Exploration is only one part of what makes FRACT tick. The tock of the metronome comes from the game’s puzzles. Each instrument has a specific puzzle type which increases in difficulty as you progress through them. The block movement and pad rotation puzzles were fine, but the last laser puzzle in the bass area had me tearing at my hair a while. Overall though I didn’t find any of them prohibitively difficult (though the ease of a majority of them may disappoint hardcore puzzle game fans) and FRACT always allowed me the freedom to leave any given puzzle to explore at my leisure. I would have to come back to it eventually if I wished to see the end, but the lack of pressure really goes a long way towards making even the hardest puzzles easier to forgive. I’m glad to see games like FRACT and Ether One taking this stance.

The way the sound design is so keenly and closely tied together with the puzzles was enough to make me smile as every solution came together. Starting off in an area, the puzzles were very basic and the sounds those areas produced once fully activated reflected that. By the time you’ve hit the end of the series of puzzles for a given color/instrument, the puzzles have added new mechanics over time and the resulting sounds that blast forth have additional layers of complexity. It really builds up a feeling of progression. Instead of a simple pat on the back for completion and shoving the player towards the next goal, you’re allowed to enjoy the fruits of your labor.

As you complete puzzles which slowly teach you vital elements of constructing tunes you unlock various tools to use in the in-game Studio room. The further into the game you get, the more you’re allowed to add and tweak into the track as you work. It starts off small with only a single loop sequencer and bare minimum controls over the tone of the digital instrument. By the time you’ve completed the entire game, you’re handed an impressively beefy DAW that looks as awesome as the sounds you’re able to make with it. While it is still limited and won’t replace your Reason, ACID or even your old copy of Fruityloops burned to a CD from a decade ago, it serves as an excellent introduction into the world of digital audio production. FRACT OSC is really a musical instruction tool masquerading as a videogame. To make things even better, the game has a built in export function and the dev is totally cool with users making commercial tracks so long as the loop work done with FRACT’s samples were all done in-game. A tutorial to mod in your own beats has been promised as well.

By the time I reached the end of my musical journey my ears were ringing and I felt similar to those nights after a gig. I’d emerged from the 8 hour rave session that I conducted for myself and myself alone, nary another ear to hear what reverberated through the cavernous area but my own. With every box aligned, switch flipped and cogs rotated I had brought life to these dead hills. As though Holy Mountain had been redone as a living Demoscene file, I had seen the secrets of this strange land from the very tip of its highest cliff to the very bottom of its deepest trench. I overlooked all that I had conquered and felt that it wasn’t quite enough. I retreated back to my lair, dark and still, slaving away for hours on what was to be my next song. I’d earned the right to control this giant machine and make it bend to my will. If only because I demonstrated that I understood what it wanted.

It wanted to make you move.

It took a few failed attempts before I finally really got into this game, but I'm so glad I stuck with it. FRACT does not go out of its way to tell you what you're meant to be doing or how you're meant to do it, and indeed my first hour was spent utterly lost and wandering around the (admittedly very pretty) landscape, accomplishing absolutely nothing. That frustration led me to put it aside for a few months. But if you stick with it, you'll eventually begin to figure out this game's secrets. By the end of my playtime with FRACT I could start it up knowing exactly what I wanted to do, where I wanted to go, and how I was going to do it.

In FRACT, you're plunged into the trippy, Tron-like world of a gigantic yet dormant synthesizer. As you progress further and further, you'll gradually begin to bring the beast online, unlocking more and more of its features that can ultimately be put to use in an actual sequencer (your studio, as the game calls it) which you can visit at any time. This is a game where completing all the puzzles presents you with an actual reward - a fully functional digital audio workstation that is simple to play with, yet deceptively powerful under the hood.

If you liked Portal's method of first-person-puzzling, and in particular if you enjoyed the dynamic nature of Portal 2's music which adapted to your progression through the puzzles, you'll likely enjoy this game. It does require a bit of initial time and patience, but it pays off in spades.

A highly original audio visual puzzle experience for the thinkers among us. The game plunges you into bowels of some weird alien musical instrument. Its starts out pretty lifeless with a little colour but as soon as you start solving various puzzles it starts to come to life with synth sounds and bright colours. Its like a cross between the Tron world and close encounters of the third kind mixed in with some very John Carpenter type sounds. Some of the puzzles can really leave you scratching your head. Back in the main hub as you unlock different areas you gain access to some very cool sound controls. The environment surrounding the hub comes to life as it plays your musical creations.

10/10 Recommended for puzzlers looking for something different.

Overall: You're inside some sort of machine that makes music as you activate its various parts by solving puzzles.

My rants and raves:

* Brilliant, original idea. I love the music-machine feel to the game.

* The puzzles do not give any sort of instruction, and give little indication of whether or not you're getting closer to the proposed solution. You are given a toy that is 100x more complex than a Rubik's Cube™. With no instructions and no idea what the winning conditions are. Good luck.

* The developers tell you to explore this vast world in order to activate the machine totally... but give you no map. I recommend Youtube walkthroughs if you're a completist. The Steam achievements for this game are not very clear, either.

* The game, with its Tron-like feel, at times resembles Las Vegas. Everything is lit up like an arcade and you have no idea where you are supposed to go next, or what is activated and what is not. The lack of communication (e.g., score, progress, direction) with the player is terrible.

Unfortunately, while the game scores great originality points with me, there was far too much else that I found lacking or frustrating so I cannot recommend it. I hope to see a sequel or expansion with some of these issues addressed.

an audiovisual journey through unknown landscapes and machinery. On the way you solve pretty simple music based puzzles with sequencers and other stuff. Sounds and looks AMAZING

Edit: I wish it had a drum sequencer tho, that would have been kickass

Wasn't sure what to make of this initially, but the quirky retro-clean graphics and deep music really did pull me in and refuse to let go. The initial puzzles felt a bit on the easy side and didn't offer quite enough variation, but it all works as a sort of chill out deep relaxation vibe. The big 'final' puzzle, the one that gets you the full synths to play with on the music creation side, that made up for everything though and was a blast.

Must have for anyone who likes funky indie exploration games, electronic music, synths, pretty colors, etc.

A first person puzzler i've been waiting to play since i've seen the first presentation video while the game was still under development. The puzzles aren't very numerous but they are all musically rewarding. As you go on, the dark monolithic world of silence you explore progressively turns into a landscape of sound and primary colors. You control your surrounding as you would an audio creation sofwate; only with a few keys and a mouse. No tricky controls or ninja reflexes requiered. The musical enviromenent make you feel like living in a "boards of canada" album. I've spent most of my time playing with the sequencer in studio mode and even managed to record a track :) I recomend this game to anyone into electronic music or adventurers not affraid to explore of a world made of sound.

This is a tough one and I'm going for 'not recommended' only because I'd like to highlight a fairly big issue which stopped me really enjoying the game as much as I'd like.

I love the concept, I love the visuals, audio and atmosphere and I like what the game is trying to do overall - however.

Whilst I normally prefer games which avoid holding-my-hand, I'd like SOME CLUES what's going-on and I'd like some feedback when I make progress please!?

Fract OSC isn't interested in doing that, sadly. It remains almost entirely abstract and leaves you to work out if you

a - have finished a puzzle
b - are in the wrong place entirely/unable to finish it
c - just making funny noises which were nothing to do with the game at all

After a while I got a bit bored of it - you start to go around in circles, wondering what on EARTH the developers were thinking - whether they believe players to be psychic and able to realise what they intended.

If you're happy to tinker and are perhaps more 'in tune' with the developers you might get on better - but I can't help thinking this is a game which wasn't played outside the development team until after release and hasn't really been polished since either?

A neon-colored non-linear walkabout music-enhanced puzzle game about a synthesizer world, with a flexible synthesizer/sequencer studio being gradually unlocked as you solve the puzzles. If you like any of the above, try it out. Approx. 5 hours long.

FRACT OSC is a pretty great and unique game. It's an adventure/puzzle game (sort of like Myst) with great visuals and music. The music is the central element of this game. Each puzzle creates music that builds up as progress is made, creating the soundtrack for that area. There's very little direction or instruction in the game, but it's usually not a problem. The puzzles are satisfying to solve, but aren't too difficult.

There's also a studio mode that gradually opens up if you want to use the synths and sequencers to make music or mess around. It's fairly limited, but pretty easy to use and songs can be exported (as WAV) or uploaded to youtube.

FRACT OSC is great and I definitely recommend it if you like the graphics & music. It's not a very complex or long (~4 hours, maybe) game, but it's a unique experience that's well worth it.

Wow. I'm stunned at how amazing this game is. I can see that it's not for everyone, but if you are at all musically inclined, enjoy logic puzzles, and don't mind it if a game leaves you to figure things out for yourself rather than telling you where to go and what to do, I cannot recommend this enough. I'm absolutely in love.

Gameplay is similar to Kairo: You're dumped in the middle of a strange world full of broken machines, and you have to figure out how to turn them all back on. But with music, and with much nicer visuals. And also, as you solve the puzzles, you unlock tools in your very own sequencer for you to use to make your own music.

+Totally original game concept
+Simple but beautiful visuals
+Large "world" to explore
+Great puzzles - others have said they felt lost and didn't know how to solve the puzzles, but I haven't had any problems; I think that if you're musically and/or logically inclined you shouldn't have any trouble knowing what to do
+Stellar music - the environment makes its own dynamic music, and you make music; even solving the puzzles is a process of creating music
+Contains an actual sequencer for making your own music

-Possible to fall off of terrain and get stuck, so you have to start the game over (be careful!)
-Not suitable for anyone who likes a lot of guidance in a game; easy to get lost/confused, requires patience
-Probably not a good game for anyone who isn't into music

Picked this up on the Eye Candy 2 Humble Bundle for 10$. 100% Worth the price.

You're stuck inside a dubstep music machine thing that makes dubstep music
New and interesting mechanic for solving puzzles
Puzzles are interesting and different
Tron like world
Huge open world, almost everything is connected in one central location
You can make your own dubstep

Unforgiving if you happen to miss a hint ( Take screenshots )
Sometimes the moving plateforms can be glitchy ( I fell through a couple times and had to redo the whole puzzle )
Don't know if it's just me or not but sometimes random framerate drops when interacting with certain objects

If you're into exploration games with a interesting visual style and awesome music then this is a must.
Also I recommend playing with headphones.

I am not kidding you, this is the most amazing thing ever. This is probably my favorite thing ever put on Steam. You make music when solving the puzzles, you unlock awesome more music making things, then you can go and play around with making your own music.

Hoenstly though, sometimes the puzzles are rather ridiculous.

A facinating game full of excellent puzzles for the musically inclined. My only criticism is that the world can just feel like a connective tissue to get you from puzzle to puzzle rather than having an reason to exist of its own, but a beautiful, enjoyable puzzle game that I'd highly reccomend.

A walking simulator that is surprisingly good.

I was really worried booting this game. I expected some really obtuse puzzles and I was afraid that after The Fall and Kairo, this will be another game that may be ruined by this aspect. Other than that, 3D Exploration games have really bad reputation recently. Fract OST shows that this genre can have some pretty nice games.

Firstly, the world of Fract OST is very immersive. Ambient atmosphere is really strong in this open-world hub that you are challenged to explore and solve. It was a bit overwhelming at first, but after a bit getting used to, the exploration of this strange world was a pure joy. it's obvious that devs really tried to win you over with this part of the game. You get achievements for discovering some particularly interesting and optional spots in on the map, which feels really rewarding and it's sign of the far greater design choices that constructed this strange world of synthesized music.

Puzzles are not all that great, but they for the most part very straight-forward. They rarely vary in types, but this lets you focus more on exploration that searching thought Steam Guides which is all great by my book. Those still are good enough for enforcing that feel of reanimating an ancient machinery that was broken for hundreds of years. In conclusion, puzzles are not amazing, but they don't break an immersion by any means.

Overall, Fract OST is a solid proposition for players loving exploration. There isn't any grand backstory, plot or anything like that to discover and yet it was a pleasure to be there in this place. If you don't like Walking Simulators, then I'm not sure if it will change your opinion about the genre, but it's worth a shot. Fract OST, in opposition to other "famous" similar games, have a genuine challenge and you won't be handholded.

I was a beta tester for Fract OSC. Getting onto the beta test program was a joy, as I was very interested in the game beforehand; it was lovely seeing the game make strides towards completion, and here it is.

Fract is one of the most original and ambitious indie titles of the last coupla years in my opinion: it marries music and first person puzzle gameplay relatively successfully and it manages to give the player the feeling of being utterly lost in a pulsating, cold yet oddly comforting machine.
Some of the puzzles are slightly fiddly but most of them are decent - nothing too complex, really, though some of them require the player to fully explore an area and take mental notes.
It looks very nice, though I have to say it might not run very well on low-end systems (the devs have done a lot of optimization though); the audio and music fit the atmosphere perfectly, and completing a puzzle feels very rewarding because of the interaction between sound and world.

The studio mode might be slightly simplistic but it's a ton of fun and you can create mighty beats with it - it's a great bonus and I wish the devs will expand on this either with updates or a whole new game.
Recommended if you like toying with music and unconventional games.

This game is kind of like what your role would be as an invisible custodian in Rez that took care of everything behind the scenes. A musical verison of Antichamber without the gratutious obtuseness.

I Bought This Game since i'm quite intrested in synth, and this game had quite powerful enough features and nice modulation. Every part of "synth" is unlocked as you progress through the game.

When i'm quite lazy looking at DAW , i hook this game to find another fun-way to randomly put some note at the sequencer while blindly sound design at "three-given-synth". Save Preset, load it another time. Save project, load it another time. While Direction where to go quite confusing, but the low-poly is fascinating in it's own way.

Even the game is have some issues like some "dropout" (even i low all the setting) at my laptop, but it run so smoothly in pc.

Try and take a look for different kind of journey that might lurking in this lovely-synth-puzzle-oscillator :)

Well, I just finished FRACT OSC, and I can safely recommend it. If you were a big fan of the MYST series, like I was, then this is perfect for you.

There is no real story behind this game, and it invites you to use your imagination, to explain why everything is what it is. From the visual and aural feasts you are given, you draw your own conclusions as to what the civilization was like. There is virtually no text within the actual game, instead relying on pictures and diagrams to relay information. Music is heavily used for artistic effect, though many of the puzzles do not require music to solve. Instead, having an iPod or Phone handy to take quick pictures of diagrams is useful. This game requires an awful lot of backtracking, so be prepared.

Beware, to run this at a constant framerate you need a decent rig, or to turn down the view distance. However, your mileage may vary. The options menu is rather sparse, lacking even a rebind keys option, which forces you to use the default bindings.

This game uses flat textures and polygonal shapes to create the terrain and buildings, and personally, I think it pulls off the look quite well. For such a simple design, it is quite beautiful.
The music creation tool is not something I have experimented with, but if you have any experience with music editing programs, you may find use in some of its synths. Again, your mileage may vary.

In my opinion, this game does not neccesarily warrant more than one playthrough, but if you have the patience to finish the game, you should have the patience to find and collect the achievements. I'm going to be searching for them myself, as I haven't perfected the game yet.

In conclusion, this game is beautiful. The art style is wonderful, but the puzzles are not for the impatient. Many of them require fine tuning and experimentation, and some of the later ones require backtracking. The options menu could do with more, but it is forgivable by a game so pretty.
