A very cool, innovative puzzle platformer. I like the simple graphics and the concept of levels having multiple ways you can beat it, however, a lot of things are very frustrating.
Puzzles are way more precise than they feel like they should be given the slippery controls. There's no indicator as to how much jet fuel you have, so there's no way of knowing when you're about to run out (which makes levels like Volcano and Tennis, which have tons of enemies flying around in the middle, way harder than they need to be).
