Lovely game! I especially like the narration!
I think it is a bit too hard though. The hit registration doesn’t seem to always work (or is the enemy blocking? I can’t tell for sure). It took me at least a dozen tries before I got him below 50% HP, at which point he ran out of the map and the below error popped up. The game seems to have frozen afterwards.
It also seems some animations are missing (e.g. the player doesn’t walk).
