You press the button and the door slides open. You dive in and it slams shut behind you, locking the sloth inside. You breathe a sigh of relief, and continue following the map. Eventually you come to where you would expect a hatch leading outside. However all you can find is a fairly small hole in an aluminum plate in the ceiling. You notice a flamethrower lying on the ground. If you used the flamethrower to heat up the plate, would the hole get bigger or smaller?

You notice the tunnel continues a bit beyond where the map ends. Perhaps it would be wiser to continue on if you believe the hole would become smaller. Using a flamethrower in such tight conditions is very dangerous. What do you do?
