Demo Day 50

With version 0.50, I've added a new, unfinished level (the meat factory, which comes after the theater,) a ton of bug fixes, balance changes, art updates and some other general additions such as checkpoints at the start of levels. I still have new weapons, enemies, items and features to implement, so this is still a very early preview of what's to come. Most animations are missing from enemies. All that said, I hope you enjoy!
