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.
