EXTREMELY good art style, really stunning! It stands out with a unique vibe amongst all the other games in the jam. And the concept here is great, but the unclear interface made it really difficult to get very far. I loved the effect of the final boss bursting out of the card but I couldn't beat her even on easy.
It was impossible to tell what move the enemy was using at any time, it was really unintuitive to have to heal by clicking on an enemy instead of the party members, and the stats at the bottom would keep showing whoever I last moused over but with the name of who's currently attacking. HP also never went down on the display unless I moused off and back on again, making it hard to tell who'd just been hit and how hard.
I think it's awesome what you've done here, its very well fleshed out and really has promise. Keep up the great work! - Bonnford
