I had a great time playing this game! Very original concept, it took me a few tries to understand that you should rush to the chests and open them before a key breaks that you need, and having to dive in there as fast as possible and not take too much damage while you open the chest trying to still out-maneuver the baddies. Then fighting the boss I was just running circles shooting arrows until my down key broke and I got stuck in the corner just barely losing the fight. I popped off a little when I finally beat the game :) so much fun!
Some small suggestions would be room diversity (as in, right now the "right" key is the only crucial one, making dungeons with a more interesting layout could definitely spice things up) and perhaps more enemies you need to use a bow for (except the boss). Great game overall! Definitely my favorite out of the jam so far.
