Very cool idea. Definitely needs improvement in controls and graphics. It'll make the game feel much crisper . 

Keep developing it bro.. nice efforts

Nice little idea. I didn't know the coloured blocks were enemies though so tried to jump on one when I got the yellow colour :). I would tighten up the controls though, it felt quite floaty when jumping which didn't give me a sense I was in the world.

This is a good idea. I had something similar in mind when the Jam started. Glad to see somebody implement the idea. Good job!

Had so much fun playing this! the concept is absolutely amazing. But for some reason the player sticks to platforms when he's colliding at the right or left side of the platform and wont fall down. other than that i enjoyed the gameplay :).
