“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

In Fract OSC, you explore a desolate alien landscape littered with derelict machinery, beautifully realized by simple untextured polygons shot through with neon and displayed using a graphical filter reminiscent of CRT interlacing. Rods of light, pulsating liquid columns, and crystal lattices respond to your proximity with bursts of sound, the stuff of music flowing forth from the ground beneath your feet, waiting to be harnessed and organized.

As you wander, you make inferences about the structure of the world and the function of its technology. You notice visual cues that prompt you to engage your interact mode in specific places, and you discover various pieces of information or interface superimposed upon objects around you. Before long, you begin figuring out how to get things working again, and this abandoned place pumps and glows with activity and color.

In the course of solving the world's puzzles and restoring its infrastructure, you construct bits of music through devices that subtly teach you the basics of music programming while incorporating your solutions into the soundtrack that results from the reactivation of key facilities. Sound is all generated on the fly using a unique music engine that is constantly working in the background, and, as if the game itself wasn't enough, Fract OSC doubles as a robust synth sequencer with exporting and automated Youtube sharing functionality.

Playing Fract OSC has been one of the greatest gaming experiences of my life. I have felt so much wonder and joy while discovering its intricately crafted and interconnected world. While I grieve to have finished it, my gratitude is far more pressing, and so I urge you: Please buy this wonderful game.

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.

Just don't buy if you're on a Mac. Two months after launch, the developers have yet to fix game-breaking sound issues affecting a large number of Macs that are well above the minimum specs (take a look at the forums). There's no word on when or if they'll ever fix this problem, so unfortunately steer clear for now.

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

FRACT OSC is an exploration/puzzle/music buff’s wet dream. It’s hard to articulate how FRACT can make you feel. It’s most certainly an unconventional experience and arguably a one-of-a-kind art form so I’ll try to spoil as little as I can.

FRACT OSC is reminiscent of atmospheric adventure games like Myst. After a very brief introduction to the simple controls, you find yourself immersed in a dark and hauntingly silent underground world. You are given no clue as to where you are or what you’re supposed to do. This may sound overwhelming at first but once you take the first steps you realize there’s a fairly guided and intuitive way of navigating this world.

The Tron-esque and awe-inspiring open-world of FRACT is filled with massive structures, glowing towers and dormant devices you attempt to restore. But despite its mechanical and desolate appearance, the world feels oddly organic. As you approach its objects they react to your presence by expanding themselves and/or giving off delicate melodies.

The exquisite post-processing filters and radiant geometric structures produce a vivid yet dark ambiance. I found the landscape and architecture so jaw-dropping I couldn’t help but taking dozens of screenshots throughout my play-through.

The puzzles are especially appealing because as you interact with them you shape the soundscape around you, the puzzle structures emit different tunes which ultimately burst into a full-blown symphony and explosion of light upon completion. This incredibly cool way of rewarding players makes solving puzzles feel more like a creative process rather than a hassle.

Phosfiend’s work is so remarkable because they managed to create an incredibly rich and immersive experience in a completely unique setting without using a single word or any sort of narrative. It’s just fantastic to see everything gradually come together and rise to a beautiful climax.

On a side note, I recommend using a controller for a more cinematic experience that can only be achieved with subtle movements of the analog sticks; You can still use the mouse for faster puzzle solving.

The game looks beautiful with its minimalist, TRON inspired style, and the graphical animations and reactions are outstanding, a good variety of puzzles with unique styles to solving them, plus they made everything simple but complicated in the puzzles you solve, and having an actual music editor in a studio like area where you can make your own song for you to save, export them and share to anyone.

I would say the game is a mash up of Antichamber’s simplicity, some of the feel of NaissanceE’s atmosphere, TRON’s visuals, and 80s-90s ski-fi hacker sound SFX, and we have FRACT as a lovely result.
