Nice lil' arena map. I couldn't find the exit after I killed the cyberdemons though, IDK if I was missing a switch to open those doors or if I need to update my Doom Retro port. I missed out on a weapon or two until the final fight (I was running around trying to provoke infighting for the first two phases) since I didn't figure out what those switches on the sides did until then. Maybe the FLAT on those could be a brighter color like blue to help it stand out amongst the darkness and monsters roaming about. GG.
