Really interesting! I can't believe you were able to cram in multiple opponents, a card shop, deck building, an element system, all in the time span of a game jam. I really really like all the unique card art you were able to make. I love the idea of crafting my own deck but I think alice was maybe too easy of an opponent to really be incentivized to try to craft something stronger then the default one i was given.
I think you have soooooooo much content here, maybe it would have been better to single in on one part or ax something, just for the sake of the jam, otherwise I think this is a really excellent start to something you can (and should) keep working on.
Had fun, well done!
