Kind of a misnomer.
Seeing as how you don't manipulate gravity in any way, the game is really more about manipulation of the mass of convenient boxes. Nitpick aside, the controls for the game are floaty and awkward. The character has no fluid run-to-jump, instead taking a half second to pause, negate all momentum, and then lurch forward in his jump animation.
He seems to slip and slide everywhere and the platforming suffers for it. I don't know if it's just poor hit detection or sloppy programming but the character often tips off smaller platforms unless he lands on them just perfectly. As far as normal platforming convention goes, while boxes may be under the effects of physics, a character model should be able to stand perfectly balanced on any ledge as long as some part of it rests on the ledge.
Other than that, the music is uncomfortable and creates a sense of unease, which is the worst choice possible for a laid back game like this. Level design was average, simple puzzles and simple solutions made for an easy experience as long as glitches or aforementioned control issues didn't get in the way. Not a bad game, but certainly an unpolished one.
but buggy as hell, many times portals would enter in a infinit loop, other times the character would just keep walking to a direction..
One thing though, on level 12 I got caught in an infinite loop, and then I tried restarting the level, and I was still in the loop. If you submit a sequel to this game, try to fix that problem okay? I'm pretty sure that I'm not the only one that has that problem.
Just needs a little polish...
Great atmosphere, fun puzzles, very decent controls ... honestly, with so much great effort put into, I could ask that there was a bit more polish all around.
Great game :D
one slight problem though on level 19 i sent the ball through the portal then folowed it and got stuck in an infinite loop
