I like the concept. The writing is pretty interesting and funny too.
Couple of bugs/issues I noticed:
- If you give up and go back to title, then start a new game, it gives you back your old deck (in addition to letting you pick 3 new cards.), while also starting you at the same stage you died at. And if you do so after beating the third boss, you fight nothing and only have 1 slot. Easily fixed by closing and restarting the game though.
- Reroute Anger can't be dodged?
- See Colour always deals 4 damage, even if the tiles resolved by Priestess and Deacon are of different colours? (I used a green and a gray, I think it was dodge/rest, and still took 4 damage)
Also managed to beat the 3rd boss, didn't find it that hard, tbh.

Quite a good game overall!
