About This Game

In the year 1905, Albert Einstein published the theory of special relativity, suggesting that nothing could move faster than the speed of light. What if any mortal could break that constant? Stretch it beyond its limits? Would human beings finally be able to find a way to cheat death and win over immorality? Or is it Chaos that follows the manipulation of time and gravity?

Constant C is a 2D puzzle platformer with two core gameplay mechanics - Gravity Shifting and the Time Field. Using these two mechanics in the game, the player controls the momentum of various objects to complete each level.

Dive into the world of Constant C, where rules of fundamental physics no longer apply. In a space station far away from Earth, mysterious events have triggered the distortion of time. Journey through the game as a lone robot, who uncovers the truth behind the incident step by step, and finds the purpose of his own creation.


  • Gravitational Shift + Control Time Flow = Momentum Manipulation
  • Over 100+ mind-twisting levels
  • 2D skeletal animation with cute character designs
  • Created a unique futuristic, mysterious atmosphere with beautiful lightning
  • Kickass soundtracks

I've play this game on Desura. Puzzles are well design. Make your hurt your brain when you are struggling, but also feel very smart when you finally figure it out. I highly recommend this game to anyone that wants an interesting and challenging puzzle platformer, or anyone that just like something new and fun. Music is fantastic. The new Time Attack Mode really is very intense. There are also a lot more new Levels in Time Attack Mode!

Great puzzle game with good level design and nice soundtrack. You play as a robot in a space station, unlocking abilities to control gravity and time as you go. Around the robot is a small radius that affects time/gravity, and you can control that on a larger scale as you progress through the game. These abilities affect items to help you platform and collect parts to save the space station. [Added]: this game will make your brain hurt :p

It's not a forgiving game and you will have to restart the level sometimes if you are unable to reverse a mistake, but the good thing is they designed the rooms to be broken down in short intervals so so far I have not gotten overly frustrated. Learning in this game is very rewarding - every time I die (oil splatters will remain on the screen as a reminder!) I come back armed with what I learned and the game will congratulate you on that every single time and it is oh so satisfying. You also gradually unlock the backstory of the space station and yourself, which is another nice touch.

Really enjoying this game so far, and hope others can give this little gem a shot as well!

The descriptions and preview video for this game are misleading. Yes, you play a mighty space robot with superluminal powers of gravity manipulation and time-distortion, fit to solve platform puzzle mazes and collect trophies. However, under your matte-black stealthed paintwork, your body is biomechanical blancmange. Your ninja-coating is actually a sweet sugary crust coloured with squid ink. You will want to run away from many environmental elements. You will be afraid, and you will die. A lot. So much so, you will even get achievements for dying the most.

The levels are fairly well-designed puzzles involving physics which is quite "oily". Moving about feels like gliding on an oil-slicked surface; rarely will you be able to get objects to move the exact same way twice. You mainly interact with environments by moving near things to cause them to move, and by adjusting gravity in three directions. Causing objects (and you) to fall about. Haphazardly chaotic at first, then merely dangerously with more skill. This will cause you to die a lot, because touching almost anything which moves within your time-distortion field causes it to summarily destroy you with great violence. Sometimes falls no more than twice the length of your character's height cause you to explode. Anything falling on you causes you to explode. Touching anything which looks remotely harmful causes you to explode.

Thankfully there are no lives in this game, and restarting the level is a matter of waiting out the inevitable explosion animation (which is mercifully short). It is likely the restart button will be pressed early and often in anticipation of subsequent attempts. You will also lock yourself into various puzzles from which your only way out is suicide in order to restart. To give a basic impression of the game would be to say players spend most of their time quietly contemplating static puzzles, before dying over and over trying to solve them within the confines of the physics engine. Eventually, the frustration at things never quite falling the way you want them to will make you quit for awhile, unless you're being paid by the level, or suffer from obsessive-compulsive disorder.

At the time of writing, the "kickass soundtrack" hasn't kicked in yet. Don't be fooled by the upbeat tune in the preview video, I've not heard anything like it after hours of play. So far the music has been very soothing, minimalist, or so atmospheric as to be barely present. The writing comprising the plot is an interesting dichotomy, because there are many child-like elements interspersed with mature ideas. In my view the exchanges and monologues don't last quite long enough to be satisfying, and unfortunately there is no voice acting. Perhaps because the dialog is not the game's strongest point.

There has been a little foreshadowing of the only other active character in the main storyline. It gives away very little as to why characters do whatever they are doing, and without playing more even I won't know what nefarious deeds have wrought the situation onboard the superluminal project space station... only time-travel will tell (see what I did there?). However, I'm not sure I have the patience to complete Constant C levels at a rate which would keep me interested in the story. My seven-year-old would become frustrated with this game in about ten minutes before going back to playing Minecraft-esque games where the feeling of achievement can be much stronger. This game is like a cross-pollination of: "Super Meat Boy", "Splosion Man", and "Braid", so if you're buying for children, perhaps try those before playing Constant C or frustration and engagement failure await you.

Well made game which tests your brain and your dexterity at the same time. It has nice art and pleasurable music. With the alternative physics and the logic associated this game gives an enjoyable and memorable gaming experience.

Every now and then I come across games like Constant C, games I really like but yet my puzzle solving skills do not allow me to progress any further in game. So what do I do? I go on Youtube and watch a walkthrough or a let's play from where I stopped playing until the end, and that's what I did with Constant C.

It got to the point that the amount of time and dedication I needed to put into this in order to succeed in various levels were just too much for me, I don't mind playing games that are hard by nature, but when it involves timing certain actions with precision, I just can't do it. Call me weak, whatever -.-

In Constant C you play as an emergency robot that was made in the event of a failed scientific experiment. The game is a great platformer with a very unique mechanic, around your character there's this "bubble" and inside that bubble time happens. Well, this actually sounds weird but the plot of Constant C is that a science investigation on a space station unleashed some kind of anomaly that stopped time and it is by using this bubble device that you can actually make anything in the game. You might see a box in mid air a few meters away but once it gets inside your bubble it will react to gravity. Besides this you also have to manipulate gravity in order to get through the levels. The levels are filled with deadly traps and crates that you must use in order to survive those traps. Most of the levels takes some time to get used and figure out what you exactly need to do in order to succeed, and this was what frustrated me the most, I was just taking too long to figure out the later levels. You can select which level you want to play in a room, which you might call it a "hub", and that's where the AI that is your friend and that is helping you is located. In various levels you'll find "data tubes" which will serve to unlock later levels and pieces of video that tell you a bit of what happened in the space station when all the scientists were alive.

Eitherway, Constant C has a very unique atmosphere to it but the art style reminds me of Stealth ♥♥♥♥♥♥♥ Deluxe so if you've played that you know what to expect. If I had to criticize one thing about the game, besides the fact that I found it immensely frustrating, was the fact that I didn't really liked the music but you might do. In the end, you can't go wrong with Constant C if you're a fan of the genre, you should totally get it and play it, if you end up getting mad, like myself, just give it some time or do what I did and watch some vids if you're curious about how the story unfolds.

Only on the second set of levels, but this game is pretty relaxing ... I'm just sitting here playing it and watching an episode of The League ... overall smooth, great with controller and entertaining thus far.

This is a really fun puzzle platformer that's all about controlling gravity. The physics are nice and smooth, the art is neat, and the soundtrack is great.

I loved this game. Even though the story and dialogue are a little ho-hum, the puzzle design is great. If you are a fan of puzzle platformers definitely get this one. Sort of like a 2D "Portal" with a bunch of small "test chambers" that you progress through and pick up new gravity manipulation abilities as you go. Difficulty level isnt that hard unless you try to pick up every research cannister as you go. Some of those are quite tricky but really make you think.

One of my favorites of 2014 so far!!

This game has a very solid, unique mechanic that works really well - objects don't move unless they're close to you. This is a great mechanic because it creates interesting dynamics and lets you take the puzzles at your own pace. The gravity shifting also synergies really well with the time manipulation.


While I like those mechanics, the game suffers from poor pacing and uninspiring level design. The difficulty curve could be more consistent, and some things could be explained a bit more, but my biggest gripe pacing wise was the time cube thrown in at the last section. It's essentially a second you which only moves through gravity, and it's another mechanic I really enjoy, but it comes in too late to be used very much.

The game boasts 100+ levels, but here's a rough breakdown of them:
~20% I'd call easy enough to be filler levels
~40% are more filler levels which are trivial just to pass, but also have collectibles (Example)
~25% solid, enjoyable puzzles
~15% unclear, at times frustrating levels

The story didn't catch my attention and I didn't even pay attention to it.

I want to reccoment this game because I enjoy its foundation, but its bland level design and meh execution makes me hesitate to suggest it. At the very least, just know what you're getting into and it'll be fine. 75/100

My time played may show 75 minutes but I've actually never had a chance to play it. That time is from idling for cards using idle master. I tried to start it up today and the game just crashes before it loads up. There's a work around mentioned in the forums but it's playing the game out of steam which you lose out on the achievements and cloud save. I shouldn't have to do this since I did buy it through steam and was expecting to play it through steam.

I can't recommend this to anyone unless this was fixed but from the looks of it will never happen.

A great puzzle/platformer that is well worth the retail price!
The art/animation is adorable, the soundtrack fits the game well and is very atmospheric/enjoyable. Tons of well-designed levels, some very simple while others are rather head-scratching if you are trying to get all the Storage Device items. Be prepared to witness tons of violent robot deaths... The gravity turning element can be somewhat dizzying and certainly takes some getting used to. Poor Rescue Robot must have died 100 times because I shifted gravity left when I should have gone right... The jumping/psychics of the gameplay also takes some getting used to... the robot seems to "moon jump" which is appropriate considering the game takes place in a space station, with lots of sliding when landing, and momentum to account for when timing the jump. It does not detract from the game, but adds to the challenge.
Definitely worth playing if you are a fan of 2D indie puzzle/platformers.

Wow! This is an amazing puzzle platformer. Not as much of a brain breaker as something like Braid. But a very good game. Tight controls, great puzzles, and a surprisingly interesting little story too. Highly recommended!

Game is cool... BUT! For many ppl It does not work with Steam client on. So no achievements, no cloud sync, no cards, no nothing... I thought the game will get an update fixing all that but that was long time ago. Workarounds suggested by the dev are not fixing this. I am very dissapointed. I voted for this in greenlight :/

Your typical puzzle platformer with floaty jumping. I'm not certain if someone who hasn't played any puzzle platformers would find this game good but after many brilliant titles Constant C falls short in my books. The time has stopped and moves only in a circle around you so that when you go close to a floating box the box falls down again. The gimmick made couple of nice puzzles but wasn't enough to make me want to play through the game. The artsyle is nice if you like cutesy scifi things but was nothing special. Can't recommend this to those that have played a lot of games from this genre.
