Very nice. I can only really think of small things to improve
One: Sound.
Two: The game likes to throw a lot of stuff at you in chunks (like ten things in rapid succession, and then nothing for a while, repeat), some ebb and flow to the obstacles might be nice.
The character was cute and I liked the gameplay itself, controls were difficult to get a grasp of at first, but felt very nice once you got the hang of it.
