In Gauntlet 2, your goal is similar to what it is in the first Gauntlet game, and that is to kill monsters, collect treasure, and find your way to the exit of the level so you can do it all over again.
But, what if you can't find the exit for some reason? Those later levels hide it pretty well.
You could just stop and hang around for a few minutes
After several minutes, the walls turn into exits... all of 'em!
Which makes it super easy to find your way out, since they all work... well, at least all the ones I tried worked.
I wouldn't really recommend doing this, though, unless you were just hopelessly lost. Your health constantly counts down as a kind of a timer, so the time you're sitting around waiting for the exits to appear will cost you a lot of health.
But, hey, it's a rather safe way to progress, so if you want to do that, I won't stop you.
