Really cool concept! I love trying to strategically place the cards, and the healing circle allows for even more different strategies! Usually I would put the coin right next to the player, but with the healing circle I would put the coin around the circle. Very creative and very polished!
I got to level 14 but died because of how many giant slimes there were in my deck. I guess I was supposed to use the discard mechanic? But I never really used it so I'm not sure
