I really like the artwork - cool environment! But I feel that I'm missing something. Either the game is glitchy or I'm just brain dead. I wasn't able to set up any loops - once I started jumping it just keeps jumping - couldn't get back into a run cycle. (only way I found to do that was to push up against the left wall and hit space). Like the concept, but I wasn't able to pull it off. : - (
(Also, couldn't figure out the function of the blue crystals other than to just make you stop, so yeah, I'm probably brain dead. )
