Beyond our world, there is an entirely different reality – it looks like a labyrinth of endless corridors. Any careless traveler can get here, but not everyone can get out. You got here by accident and now you need to find a way out. There are many doors and only one leads you home. But there are also monsters that will hunt you down. Fight back and find your way home. Getting lost here is easy, so be patient and use your wits to find your way back. Also, try not to get caught by the monsters.
