Like you have seen, this "Loop Map" doesn't have a single hole to escape. Howeve, a room that has a hole can be accessed through a certain path. To start with, the exit is at the ceiling of the first room. What? This might frustrate some of you because some of you might have already checked the ceiling! However, you can't see it from the first place. They are activated once you are out of the first room. So you HAVE to make a loop around the map to meet the right arrows. There are only two arrows that leads to the room of exit and they can only be seen once you are out of the room.
