Here’s an idea: gameplay sort of like Goblin Cleanup, you have various chores you have to do cleaning and arranging the various levels of the tower at night while the dragon is home, and your work has to pass an inspection. Then during the day you are locked in your room, and have some ability to watch a prospective rescuer attempt the dungeon crawl without your direct input. But you can strategically arrange items, enemy spawns, and Dark Souls style hints to try to tip the scales during the chores phase. So kind of like a tower defense game in reverse where you are trying to lose.
For that you would have to completely change how currency is issued and managed. Money is created by being borrowed directly or indirectly from the central bank, and the reason it is possible for those loans to later be repaid is because even more money is loaned out later, so it’s not going to be a game of musical chairs where there isn’t enough money going around to pay them all back, they keep bringing in more chairs. There is always an increasing amount of money in the system, and they make it that way on purpose to keep things running the way they want them to.
Personally what I hate about this setup is, a person who meets the requirements to obtain a business loan can now take this money that was created out of thin air, use it to coerce labor out of people who have no way to get money other than working, and keep the profits. What if our lives would all be better off working a bit less? Too bad, that decision isn’t up to us, how much we must work is indirectly decided by monetary policy, which the average person realistically has zero influence over, and the goal is a high level of “economic activity”, ie. as many people as possible subject to financial coercion.
