finished it! the ending was a little underwhelming, but totally understandable for a jam. that last room was pretty intense! really solid little game. i enjoyed the puzzles and combat was fun. i'd love to see more done with this .
i did find a way to cheese the enemies though. you can just run up to them and spam attack and hit them 3 times before they can barely start moving. you probably want to add a little bit of a cooldown on the player's attack, and maybe a longer cooldown on the enemy invincibility after being hit (if they even have that at all).
