A great puzzle game marred by the dumb and obnoxiously vocal companions you're supposed to rescue.
The whole point of the game is to escort the various trapped citizens in a level to the rather obviously titled exit. They're all totally incapable of rational thought and thus you must touch them to let them know you're there to help, where you can lead them around and order them to do things. Adults can perform most of the moves you can, though they cannot jump as high or as far. Children can duck into small passages and are light enough to not disturb a weak floor. The fat people are almost a liability, since while they can push massive blocks, they are unable to move over anything higher than a single square without your help and the help of another adult to yank them up. There are also incapacitated guys who you have to carry over your shoulder (severely limiting your range of movement) or dump on a stretcher. There are elevators, pressure buttons for doors, ladders, ropes, fires and fire extinguishers, picks for cracked walls, pushable blocks, etc. All of these pieces combine with the various strengths and limitations of you and the various people in your level, and more often than not require a bit of thought to avoid a dead-end reached simply by pushing a block one square too far.
So the general concept is pretty solid. Is the game fun? Kinda. There are a couple of minor issues that end up being less minor than they would initially seem. One, your companions are controlled by moving the right analog stick and clicking it to give orders. Fine. Only problem is they're as dumb as stumps, and most of them time are completely incapable of climbing a set of stairs unless you direct them first to the foot of the stairs and then the top. They also won't follow you up ladders unless you dismount on the opposite side as them, as the follow routine apparently only makes a distinction between right and left, not height. This serves to dole out a lot of frustration, especially when you're trying to get a perfect 100 score on a level and your companion keeps messing it up.
Two, the sound clips are terrible. Sound effects and music, fine, voices, hell no. Each character type has a couple of canned stranded and rescued/following clips that run on a countdown timer of approximately ten seconds. So every ten seconds you get to hear grating whiny gems such as "I really need a shower!" or "Help me will you!". The voice actress performing most of these manages to serve up some of the most obnoxious delivery you'll find in any game released in the past decade, which is made ten times worse by it being hammered into your head every other step.
It's kind of a shame, because Exit is a good game. If it didn't have the AI problems or (especially) the awful voice clips, it would be a joy to play. As it stands, it's fun, but only for short bursts or only if you have an extreme tolerance for irritants.
