This game is *hard*. I've spent like 30 minutes running around the castle and I still don't have a foggiest understanding of its layout. There are doors that are not doors and stairs that are not stairs. You enter a room through a north-facing door, but the exit is east-facing for some reason. And where the hell is the kitchen? I can't even do the first quest.
RPGM is a fine engine, but this game is a little *too RPGM*.
Edit: found the kitchen. Go south-west from the start, and the thing immediately in front of you on the next map, the one that kind of looks like an outhouse, is actually a staircase to the kitchen.
