so here goes my initial design!)
You start in a room with a table and bed → have to put a gargoyle on a stand in the middle + vases on stands to the sides
If you do it right → the way to the stairs opens [wall to the left goes up] where you can steal a gold statue, but there is one gold vase in the room, you must put it on a stand instead, in order to exit )
else… [for example if you do only a gargoyle] - first way openes [wall to the right goes up] - it will eventually take you to a dead end with a single sad candle)
It also has a cage in front of the door - I would make it deliberately hard to open just to mess with a player)
[or may be give a reward for trying - dont know yet]
