Really impressive for a first game! Having a functional menu and level select is something that is often missing in game jam submissions!

I'd recommend implementing a tutorial in the first level or two.

As you did everything by yourself, it's a pretty impressive work ! The art works great, the music feels good, and the idea isn't bad ! i like the idea of getting in a "super-state' which permit all sort of movements, but using Right CTRL and WASD wasn't the best setup i've seen for a platformer game, i admit :') 

I enjoyed this! It took me a little while to work out that killing the red guys would reward me with extra controll, but i guess that was my fault a bit for not trying it out sooner! Good stuff, cool puzzles that come from a unique set of mechanics.
