I love the introduction, that the fact that people thinking white and black are a color are not able to play with the player. (but i think i skip the tutorial about color changes when i pressed "B" to see what the punishement was.)
The movement feels juice, i really liked it. And nice landing particules too ! It really feels polished.
The game is too hard for me, to be honnest, but that's okay.
The color change was so scary because you don't really know if their is something under your feet, until you press it (and i was not quick enough to press it 2 time mid air). To me it's a really good horror game ^^.
Good job, may be i will give another go to see the gameplay more in depth.
