Glad I stuck this one out. I was able to play on my QWERTY keyboard (albeit it slightly awkwardly). I think the keyboard mapping issue you describe could be considered a "game breaking bug" and you might have been allowed to re-upload?
In any case, some of the animation and effects are really nice. Oh and the music, is spot on! :) As you mentioned, you ran out of time -- missing things like a game over screen, progress bar maybe(?), ability to pause, re-map controls etc. all would be nice, but I think the core is a really good start. Good luck with continuing to develop!
