I am looking forward to what you end up posting post-jam, because it seems like there was an interesting game planned here, that unfortunately didn't get to be made as-planned. I do think that "having a die for a head and shooting a projectile that happens to be a die" isn't really relevant to the theme, as you aren't actually "rolling the die" for the interaction; but that's a minor issue in the grand scheme of things. Best of luck on your future builds!
