The idea of an automatic platformer where you have to change the screen color for platforms to exist is neat and the character's design is cool, though as others have said, the game needs polish. Maybe you already know this, but if I fall off the platform, the character just bounces along with it's head just above the bottom of the screen for half a minute and then the "You Died" window pops up. Others have said there might be more to the game than fits in their screen, so maybe there is something I am missing, but from what I see, it would be simpler if they just died after hitting the bottom of the screen.
It would also be helpful if the controls were listed at the beginning of the game, as well as the game page, and for a note to be added at the beginning of the scene to press W to advance the text.
