You entered a hotel which was rated 5 stars! You decided to sleep in there for one day to check out how it is in there. The next day when you were about to leave, the doors to outside was locked. You look around for a worker but the place is empty, so empty that you could hear the clock ticking and your own heart beat. You see an open elevator and decide to step in. The elevator closes and is going down further down into the hotel. As the elevator opens again, you stepped out of it and looked around. The elevator closed. You see a locked door with a number 001 on it. On your left, you see a key which said 001. You go to grab it, and then open the door. As you open the door, you see another door. 002.

You have to go through all 100 doors to... escape?
