Proscriptively speaking my biggest piece of feedback was that it felt to chaotic, and I could just spam to survive forever. Do with that what you will, but my recommendation would be limiting how many dice I can throw so that I have to put each one to good use. Or you could even add two dice that I choose which one I roll, so I can save a useful shotgun roll till I think I need it. And I do recommend you stick with this, you've got a genuinely good game on your hands, not even just a good one for the jam. Were this expanded into a full on roguelike with all the obvious more interesting upgrades and rooms and stuff I'm sure you already have ideas for I could see myself putting down a few bucks for this.
