I really loved Monaco and was super disappointed in the sequel. To see it translated into roguelike form is one of the coolest things ever!
EDIT: Small issue report. When opening something that causes money to drop, the way it tries to find spots to place the floor coins can be faulty. It has a tendency to spill over into weird places instead of what might seem more sensible since it doesn't seem to work like a flood fill. As an example, the tutorial's safe can deposit a coin into the bottom left corner of the room at the top right. What would be better is if it put this coin through one of the doorways or just further into the room it's in.
