It's not quite the freshest theme idea because of the lockdown bathroom. Which is probably all the bathroom HL2DM players ever really need.
But the car that crashed through the wall made me lol! I don't remember seeing this in a map before. You could do something with that. Make it bigger or put something on the car. I don't know. It's a really nice detail. Maybe nice enough to merge it with a more unique map theme?
