Certainly has it charm, distinct art style.
You can swap places with your opponent but it's a card in the game, I think it would be better if the swap happens every 2 turns so you know when it happens and you can plan ahead which cards you keep and which you must play so your opponent doesn't get them. This makes the role swap like a central mechanic in the game, now it feels more like a side thing.
It does feel a bit empty without sound effects for the cards.
Props to you for making a card game and enemy AI in just 2 days, besides the art (both drawings and models).
