You are Steve. You venture outside the box and save Dr. Trayaurus. Yes. From TDM. If you spawn outside the tower/box go to the top and go in from the glass. You can't break blocks outside of the tower/box. Have fun!

PS: Mine to find the exit and don't break the blue clay.
PSS: Sorry for the bad picture. Why! Why did I make the walls solid blocks! Trust me. It's an OK map.
