The concept of a clumsy thief in a mage's tower is just a nice funny one, having to actively put items in the bag makes the more "active" moments more fun when you have to dash around trying not to get caught and frantically stash stuff in your bag. The final countdown of the coins is very satisfying when you successfully loot the place clean.
I was unironically jumpscared by the chair as i was expecting just chests XD
