I really nice and small game! I liked the art style direction as well as the music it was really nice!
I do have some suggestion about the game though. Firstly the first jump of the tutorial cannot really be done without the propeller and because the tutorial for the propeller comes after the jump, the only really way to continue is to feel down from the main platform in the start. I would also like to suggest adding a little more ice cream around the level, or resting the ice cream amount every time the player dies, as I did get stuck because I run out of ice cream!
Overall though, a really good game! I can see that a lot of work went it too it! Great Job!
