The only things I noticed that seemed dodgy were a couple of bleeding walls: two thin ones in the karaoke stage and one with the ATM/cigarette machine (?) by the blue neon martini sign. Not sure if these were bleeding midtexes, since they seemed to be solid walls, weirdly. But on my ZDoom the walls extended down into the floor with that same glitchy look that you get with bleeding midtexes. Something to check, at least, if you have a quick chance while Joe is presumably compiling.
Otherwise, loved the theme and little realistic touches. Gameplay was pretty gentle but engaging throughout--I made it through first try on my laptop, track-pad only. This will be a great early or opening map, I imagine.
I lol'd at the masturbating (?) archvile, too--not sure if that was your intention, exactly, but I won't be able to unsee it now! ;P
