I started doing some more on my map, but I can't really think properly at the moment. These cold tablets are making me dopey. I want to try and do some door openings triggered by an enemy death and how to make some doors stay open, once a switch has been used. Also, how do you make the switches change to the lit up version and click, after use? I tried that the last time I was working on this, but I couldn't figure it out. I made a switch that spawns Hell Knights, but that was a test.
