A new update has been added to the game. The update doesn't address all issues, but it does eliminate the immediate problems in gameplay. Notably, bleeding caused regeneration. It now properly causes HP reduction. Also, in the treasure chest room, there are multiple battle events, but the player only goes through one. Not all battle events recovered health. They do now.
There is still quite a bit of polishing to do on the battle system, for example, I didn't want there to be an MP gauge, but that's all stuff that's going to require a bit of development, though the MP gauge could be removed easily, that's not what I'm most interested in. Rather, I'd like to redesign the system to fall more in line with what I envisioned.
Anyway, this update should not have any serious bugs, anymore.
