Very original game!
I like the idea of only having one color world to help you navigate at a time.
I kept falling out of the black platforms sometimes as I jumped out of the white, so I would fall all the way to the bottom!
Also I fell out of the border on the left and right because I thought they would stop me :(
Maybe just have the needed platforms in the level?
Awesome job!
