Additional unexpected behavior: 4 - NPCs were able to shoot through boxes/floors which stopped my bullets. 5 - When dropping off a ledge, it is possible to walk into midair before falling.

Also, like many 2D games, the best way to kill something like the level 1 boss is to scroll it off the screen and spam bullets.

I did not have any performance issues - it was steady at 60fps.
