This cloud be a decent puzzle game concept. sort of like the Stanley Parable maybe??? I like the minimalist design and the instructions that does not get in the way. Although I would highly suggest binding the abilities of the player can do to the color of platforms consistently, i.e. the platofrm that locks your movement should be a different colour.
I think there is a bug where I could not stand on the red platform at all, which make me unable to finish the game. Also I would advice to only restart from the level after you died instead of the beginning of the game since it can be frustrating.
anyway, the game is actually far from bad. You can try to explore this concept of obtaining different movement options while standing on different platforms further. I would be excited to see how this goes if it does. also some audio would be nice
