Excellent production value! The fast, slippery way the character moves makes it satisfying to play. I kept feeling the urge to jump though - I don't know much about game design but I feel even a small jump ability would significantly improve the way it feels.
I found I was unsure how to complete the level until I went back and did the tutorial. I think it was because at first play I couldn't figure out what the giant donut meant. Maybe if you changed it to something that signifies an exit, like a candy themed locked door, it would make the objective more clear for players without needing an aid.
