A really fun simple character! Been a while since I've seen one of these. I really like how the Spikeball is it's own little entity.
I do have a few problems being CEZ3 is pretty much impossible without damage boosting, Enemies being hit gives you a boost but not hitting springs? and (SPOILERS) Super Maimy glitches out on the CEZ swings.
Other than that, I really enjoyed her! The Rocket is really fun.
