Beautiful game, created wonderfully with a couple of major letdowns. The keyboard controls were quite cumbersome - would have loved to have been able to use directional arrows for movement rather than having my hands hunched around WASD and Q/E/R. I also found that a couple of screens had enemies very close to their "entry point" and I would glide into them and die before I really had a chance to react. Would have loved some sound and music too.
Nonetheless, they're small problems in a game that is beautifully presented, making excellent use of the small resolution and generally feeling like an excellent, polished game.
