Great
I felt obligated to review this game, simply because so many other games on the main page SUCK and I wanted to review something that didn't.
This game is extremely well designed and very very creative. I can't say I've ever seen a game that ran quite like this, so I'm very impressed with the originality.
The controls are simple, yet allow some complexity of actions. Well done there.
The only minor complaints I can make: the attacking is so simple, that sometimes I get beat by an enemy because all I can really do is jump and smash. The enemies could be more easy to predict and therefore combat.
Also, the hover button could probably have been a diff button than the jump button, simply because sometimes I mean to hover, accidentally let go of jump, and then slam down plummeting to my death in a pit I wanted to hover over.
All in all: good job.
