Really good for a game jam entry! I love the art and music, as well as the premise. Gameplay felt a little hard to intuit sometimes (especially the blackjack minigame), and I wish the world exploration parts were more fleshed out (that'd be fun for an update), but otherwise, it makes perfect sense for it to be luck-based, it's forgiving enough to accommodate for that, and it's a fun time!
I also kinda wish that the counter for repair parts updated as you beat enemies, even if it still had to restart when you went down to 0 HP.
