You need a few more instructions, I didn't quite know what was going on initially. I thought I had good hands but was losing automatically as I didn't realize I had to click two card to submit them as my hand. You should prevent the player from continuing to the showdown until they've done so. It would be nice to have a reminder of what trap I selected as well, in some cases I wanted to play them on myself as well to change my hand. It was a little unclear to follow some of the action from the players and how the traps were working from their side, giving them names would be useful to be able to label actions and such.
The visuals and animations are gorgeous. It's got a lot of polish on the art front. Just needs a bit of framing of the game part and instruction/usability. Hope you do a post-jam version!
