Can go through the cell tables
Some areas are pretty dark
Alot of doors when opened you can see in the open state
Texture glitch on grass
imo the vent should be a vent texture or at least make it the right sound for the surface :P
Other suggestions -
Signs to know where to go, medic, disco, pool, kitchen sign etc
Signs that tell you which button opens the cells and which closes (seems pretty glitched at the moment)
other suggestions are welcome too. I'm also going to make the map a bit bigger because it's pretty small for 20 people.
