You chose to go into the right opening

Game over!

You walk through the opening that is to your right. Once you are on through the doorway, the wall closes as quickly and mysteriously as it opened. Then, a light flickers on, although it does not do much to illuminate the space you are in. All of a sudden, you hear a low growl from the corner of the room and see that the maker of the noise is giant mouse! You wonder how it is so big but then remember that you are only 3 inches tall! Before you can make a move to escape, the hostile mouse attacks you. Game over for you :(
