Hi, I really like the quality of your game. The graphics and different types of enemies add alot to the fun. Your menu is also well handled :).
Only that it's hard to differentiate between game layer and additional layers (feels like therer are too many foregrounds, backgrounds); the jump feels like overly precision based, I think it would feel better if he jumped a little bit over the platform and then land.
I would love if there were more characters to vary up the possible playstyles.
