Cool little crawler! The movement and turning are well done, the rythm mechanic for combat is unique and a breath of fresh air, the enemy graphics are charming.
I think on one of the fights I didn't hit enough notes to kill the enemy and I just got stuck on the combat with it because no more notes were coming across the screen. This could be fixed along with maybe some feedback when hitting the notes (damage indicator, enemy animation etc). The turning was a bit slow and the dungeon itself was a bit bland.
Overall a solid entry! I'd love to see more!
