just played a run of this, the cards are overpwered in fun way, i can also see this being a campaign game mode with story if you ever choose this route in future
i will say you should add some music that makes this game more addictive than ever, like those dings any time you hit enemies? they are great and maybe something of music rhythm or whatever to gain more dopamine, but I dunno if im making sense tbh
another question
do you plan to give enemies their effects like how players has one? you could copy paste some of player cards effect to the enemies' cards, but the more fun ideas is to cook up some special or unique effects for them. something like how if the king dies then the queen will double attack or something like that
by doing this it would give the players some real challenges and may push for different rewards picks (because everytime rewards comes up i always choose extra card slot because it is simply that powerful)
