Love the customisation of characters and animations. I'd suggest adding some BDSM, such as the winner tying up and gagging the loser then fucking them as they wish, it' be really hot. Maybe some BDSM cards or an option for it once you win? Another thing I'd like to see is live online  multiplayer battles where you and your opponent play, you have a timer for each turn, there could be a search for battle feature too or maybe allow us to challenge other players in a lobby or smth. Just my suggestions to improve the game x
