At first I was afraid of the walls...then I realized you could simply march through them with impunity and rack up a grand score. Many walls had their pride damaged during my playthrough but the way I see it is the walls started it...

I dig the colors and the little clouds that pop up when the player transforms.

Either the game is a bit broken or it's demonstrating a message about breaking down the walls of life.

I stopped at a 100, there didn't seem to be and end in sight, and I about that time realized it didn't matter what part of the wall I went through, I always got a point.

I mainly noticed things about the level design, so here's my thoughts on that
1) There's no ramp-up, you could have started with a couple of shapes to get the player used to the idea, space the walls further apart in the beginning etc.
2) The current camera shift places the walls too close together, making it hard to see what's coming up.
3) There's no way to make it from far end to far end right now.
