Pretty cool game! Captures the theme well and the creepy music works well.
The last dungeon was pretty tricky. Had to master the tactical retreat while swinging that sword like a lunatic!
As other reviews mention a little knockback would help as would a debounce/short invul after being hit would help also as if a pack of 5 zombies all land a hit at once you instagib even with full health.
Well done though!
