Also I found the doors can be placed only on the ground, so I cannot make the roof exit. And also I can remove column, but cannot place it if I want.
Hey! Thanks for the feedback!
I just released a new update with tons of fixes and improvements, including your suggestions! a fog slider, mouse sensitivity settings, camera shortcuts, and the ability to place doors on higher floors
Just the update that we've been waiting for! Going to try it now.
