One issue I had is that if I select two non-matching cards, I didn't see the second one. I'm not sure if that is by design.
I just submitted my first draft of my game (https://itch.io/jam/game-off-2020/rate/833423) - if you have time to play and let me know what you think, that would be great. I hope to finish online multiplayer before the end of the jam, but we will see.
