I love the idea behind the game! The overall UI explained each of the mechanics fairly well and felt very well designed, even if it was on the smaller side. It might have been better to go the full playing card route and use all 52 cards instead of 1-9 (renamed suits are probably still fine, though the icon/color should be a lot more prevalent), and maybe a bit more flair behind each of the bosses, though overall it was an enjoyable experience!
