Hey Fang, nice new area in what was once a secret area behind a 125 DC door. Very cool. (I won't blow all of his surprises in the update

)
Just an FYI, did you know that you can have the coin man lured out of the room with a fight outside the door and then brought into a certain red winged man's room. Granted, he can't die, and he won't hit worth nothing, but he is very good at taking some of the heat off of you while you slay the aforementioned red winged man.
I don't think that was your intention, and granted, it is not easy to do, but perhaps you should go into that NPCs character file and change his, what is it called, perspective or range or sight, to close or low. I forget what it is caled, but you can alter what they react to by distance.
Anyway, just thought you might like to know.
