Really nicely done.

It's like a 2D Miegakure ^^

I love the minimalism in the visuals. it works quite nicely.

For this jam I'm mainly interested to see how developer solve issues when they remove the core mechanic of their choosing and I think you handled it quite well. The position of the key to move the character and rotate are next to each other. And especially the platform you jump on changes color which relly help to orientate yourself and know which part you explore or not.

Excellent job

This is a really cool concept! I'm not sure how it fits the theme tho. Oh yeah and the controls are not that good. 

Otherwise amazing!

Cool game, but I don't see what part of a platformer this doesn't have.

this is really neat!  clever concept, nice minimal look, great music!
