Nice, I like the concept of increasing difficulty each loop. I also like the theme tie in with the minotaur trapped in the labyrinth, it's like you are both trapped within the story of good vs evil!
I definitely agree that the combat could use some refinement. Attacking in multiple directions, as well as an indicator of where the attack is hitting, would be really nice. Definitely really solid for your first entry to the jam, I look forward to seeing those improvements in your next entry!!
