I really like the game! The art is so cute and so well done I just want to eat all of them :P
The music is also well themed!
I can't really speak about the controls cause their pretty good, maybe you could have implemented different jump heights(like if you press longer then higher jump).
The main menu effect with that water is so beautiful!
One main issue tho is that when you die, then always when you jump the game restarts? Don't know if its just me but that made me quit the game and don't reach the top, the game is also not the easiest. Buts that's a good part, you should just fix that bug and I will definitely try again!
Overall very nice game!
Feel free to check out my game too!
