Here's a strange question

Theoretically this could be done in old-school Bard's Tale fashion using pictures, input password functions, and variables.  Drawing the pictures would be the easy part.  This would be a programming nightmare, I think, because it would have to keep track of where you are on the map and all the key-presses and picture combinations necessary to get around said map.  But, it's possible.

I guess the hardest part would be working with the pictures then.  You'd have to draw about...30 pictures of various hallways and doors and rooms.  And then probably do different versions of those hallways, doors and rooms.  Yikes!  So here you are, building your dungeon...and you have 120 pictures of random hallways, doors, and rooms to select from.  Yeah, have fun with that!
