I beat the final boss, but I found a bug in that even after using my health potion I was able to spam 2 and use it again haha
I wasn't able to nail the parry mechanic on anything but the bats (I think I just didn't quite understand the timing) but the juggling of the upgrades was an engaging gameplay loop as well as the ability to us the hammers to find hidden items. Combat was fun and juicy (With the slash sound and the cool dissolving death animations). I also really liked the creepy ambient background track.
Nice work!
