I'm not totally sure I get how to play... but I like the concept a lot!!! It seems like you were sort of going for like- something similar to the dice game yacht/yahtzee (though perhaps this was unintentional), but instead of scoring, specific combinations summon demons? Its a really compelling take on the rolling-combos-of-dice formula.
Also the art/general aesthetic is really nice. I like the spooky demons.
