Great game! I had fun playing this platformer.
I liked that the sfx fit with the look of the game. Although sometimes they didn't play (but that may be because it is a browser export).
I was missing the music, at times it felt a bit quiet if I hadn't picked up a green globby parasite.
I did have to get used to the fact that I retained my momentum while airborne but once I did, that no longer was an obstacle. And the movement felt natural.
