I am joining in this time with a easy-to-implement yet difficult-to-win idea! So you are just a normal guy living a normal life when you lose your keys. You have to find them before you leave the room, but wait! Is the ceiling slowly coming down to crush you? You find your keys and escape the room, but oh no! You are in another, messier room and you need to find another key, all with your doom slowly sliding down above you!
