The level has under 800 linedefs 'cos it was made on a shareware program. I've tried to make the most of the linedefs available and used almost all of what I was given. The constraints were probably a good thing 'cos it stopped the level from getting too large - it seems to have settled at a good death match size. The single player lacks a bit because of this, so I tried to make up for it by jamming it full of tricks - don't expect to get through it first time unless you're good.
Whoever ends up sticking this on their website (could be Doomnation - they're helping me on this) and idSoftware for making DooM.
None as far as I can see. Take care not to get stuck in the exit room in Deathmatch as there's no way back up to the rest of the level without dying.
