I don't think there should be exploding carts that can kill you on low max health and armour. Spent 15 minutes clearing a level, then went to hit a barrel that would give me 5 gold, only to accidentally hit the cart next to it, making it explode and killing me from full health. Then having to do this again?...
I had a bug where I used Swarm both on a boss and another enemy and for some reason it drained all my health within a second and now my Cursed Vampire is stuck in a black screen.
