This game was very short, but that's probably the only negative thing I can say about it!
The game controlled great and felt really good throughout its entirety! I would love to see more levels, especially after what you did with the last level, it seems your system was made well enough for you to start to be able to have fun with it. Also great touch with the jumping feeling really satisfying and oddly non-restrictive even with the giant ball!
Great job, hope to see more of what you do!
