Breezy, not too difficult, and fun to jump around in. It has a brainscratch-y gameplay loop and a satisfying progression of upgrades, though I'm baffled by why the ability to shoot bombs in midair is optional. The combat is pretty bad, but there isn't enough of it for me to care all that much. If I have one real complaint, it's that the game world felt a little too small; there are really only three major areas and I started to get tired of the mechanics for each one by the end. Still, I had a lot of fun with it.
