Oh wow look at that, you already found the exit! You might want to scamper out of this dungeon real quick otherwise you will be killed. You don't really have enough time to go back and look at things right now.

You can go in two directions:

FORWARD: This is the exit of the dungeon, once you leave you will probably be able to find somewhere safe to hide and not be killed.

BACK: Why would you go back? You're literally where you need to be.
