​Some bugfixes & tweaks

Version 1.0.1:

• (Hopefully) fixed an issue where stompers could push the player out of the map.
• Made some tweaks to Slendercog that should make him a little less prone to clipping.
• Added a ceiling to the elevator collision.
• Made the screen that shows up when you fall out of the map less mean.
• Made the factory marginally brighter overall.
