I really enjoyed this game! Please use something else for the level select screen; i have a trackpad. How about a nice little pause menu triggered with p?
Feels a lot like dicey dungeon, but its clearly its own thing and very fun. For me, a bit long and click intensive, at least in part because the text is so hard to read, but looks like a good idea!
Maybe to even out the randomness make it 2 coin to change a random card in your hand with a random card in your draw pile, up to once per turn? One coin would be 'fair' in that if you'd have to end each round one turn earlier in order to be cost effective, but is probably much too powerful, especially since aoe costs like 5 coins and that is at a guess only twice as powerful. 3 coins is the same as avoiding 1 damage, but theres risk associated with it, so 2 is fair, I think
On the next run I also just beat the whole game, on the new balance patch, without ever collecting any gems!!! I have no clue how i managed to do that when on the 3 runs previous to it I had run out of moves, but I guess i just got super lucky and thought really well. Anyways, that officially exhausts my ideas for how to unlock the secrets

You say the text is hard to read, what resolution do you run? We'd like to fix it.
