I would space out the new mechanics. Leave some room between introducing new mutations so you can flesh out the ones that already exits. I like how the character visually changes with mutations, though the artwork could be improved for the level geometry. Nice entry.

Nice game! Mechanics are a bit similar to my game :) I found one bug. If you use W and up arrow key, you can double jump without double jump buff :3 

Congratulations!

Great Game love it would 100% play it if it became a full-fledged game some things could be improved upon but amazing non less!!!!

Controls were a bit rough, but fun game.

Really fun game! The only thing I didnt like is the audio, its a bit too harsh. The graphics could do a bit more work but overall a great game!

Pretty fun, although the bounce can be a bit finicky. I got 7:10.

Nice puzzle platformer. Graphics are simple, but make all very readable. Difficulty is progressive. Levels are well designed and challenging. Great game.

That was fun. The idea is quite trivial but it has a lot of content and various challenges. I liked the bounce effect, haven't seen it much before. Overall, very good job!

I beat all Levels in 6:58 (Is that good?). Its a bit of a rage game, because the controls are a bit floaty, which isnt very noticeable until you collect the speed mutation. However overall its a great little game!

Cool game. I suggest turning down the sharpness of the audio. Nearly fell off my chair ^_^

Fun game! Enjoyed the variety it offered and found plenty of sections challenging, but doable after a couple of goes. Graphics and audio are just ok, but they suit the game and the screen effect is a nice little touch.
