This is insane awesome man! I cant believe you were able to get all that done in a month.
I loved the art, music, sound effects, bosses, cameos.
It seems you would have a pretty easy time converting it into a full fledged steam release.
Only critiques is I would want to tighten up the controls for bow /sphere aiming. I also couldn't figure out how to use the ability Vicot gave.
Excellent job!
