Had a bug with Demon's Maw showing up in my playable cards but not clickable/draggable for some reason. It would be useable in the next turn after showing up which was odd. Sometimes I could start my attack by pressing space but sometimes it it wouldn't work.
Had a lot of fun playing this and would love to play more! Easily the type of game I could get addicted to due to the different possibilities and synergies.
