I've definitely seen the chest one multiple times, with not having to unlock the door as I can just go through the other end! I also am pretty sure I had the glitch with the swamp too, I had it after floor 3 where instead of getting to the swamp the post-key stairs took me to the caves instead.
I was very confused and thought I had encountered a bug until I realized that oh no! The block being removed on self was fixed to actually work with the ninja armour! Noooo!
I didn't realize that with the shield spirit, every time I used the shield my weapon's damage decreased. I definitely think some clarity with what the relics do would be great. When I say that I mean a bit more detail in their descriptions. I also don't love the mana rework.
Clever little game! It definitely is frustrating how slow the attacks happen versus the enemy attacks, also dodge doesn't seem to do much (at least to me).
