Yeah, balancing was a struggle. I wanted the second fight to be scarier than the first and play completely different than the first, but I also wanted it to be a bit easier than the first, because every time you die to it you also have to redo the first fight. I didn't want that to happen more than a few times. 1st try might've be a bit too easy, though. Ideally it would take everyone 3-5 tries to beat the second fight after maybe 10 tries to beat the first fight, but that is really hard to balance with how varying everyone's skill at this kind of game is.
I wanted to make a game end screen, but I never got around to it. It probably wouldn't have been that hard or taken too long, my attention was just diverted elsewhere. I do like the peacefulness of the current ending though. If only it were clear that it was an ending.
