Snuck in a final update with a rather large amount of stuff.
The boss is more dangerous and has a new special attack.
I added some more flair to the ends of floors and the leadup to the boss.
I added an entirely new enemy type ('a').
I fixed the stealth bug. It was embarrassingly stupid in retrospect and I should've looked at it earlier.
I renamed the wizard class to "Regular Wizard." I don't know why I didn't do that in the first place.
