Hey, just played the game (loved it) and I just want to say I found a bug with the most recent version.
Once you have the armor, you can take hits without taking damage if you're right next to the dodge spot, but it actually heals the player. I think the armor can cause negative damage to happen and heal the player.
Not sure if you want to fix it, since it was useful for the final boss, but I thought I'd let you know.
Cheers!
