That was wonderful!  I was lightly frantic at times leaping into the void, even though I remembered there being a platform there ... somewhere.  The game is part platformer, part puzzle, and part faith.

I liked how you would sometimes place platforms in places where they weren't necessary for the movement, but instead served to show where the other colors of platform were.  The sudden stops after jumping were jarring and exciting, especially the close ones.

It's an elegant and artistic, but simple game.  I bet you could put together a variety of levels that all needed both of the black and white platforms, and had clever ways of showing players which ones were where only-just when they needed to know it.  AND, you could emphasize the excitement of just jumping and seeing where, and if, you'll be caught.  Your future marketing department may call it, A Leap of Faith.
