This is a great idea for a game! There’s a solid prototype here, I made it to battle 12 when I got unlucky and rolled 4 skull dice. The dice-rolling animation looked really cool. I’d say you could shorten the wait time between rolls a bit, since you do it a lot in this game. I wasn’t much of a fan of the ‘microwave’ sound when there’s one skull left, the beep felt a little out of place.
But overall, really good game, super fun and a great fit for the jam theme. Congrats
