I'm always interested in novel games, and this was one of those. Reminiscent of Lost Vikings, or even the Toytopia game that Schell Games did a few years back, you issue commands to autonomous characters to get them out of a burning building. The twist with Exit is that the characters all have different abilities (the kid is weak, but can crawl through tunnels, the fat guy is heavy, but good at pushing things). It's very puzzly, and can be frustrating when the pathfinding is bad, but if you like "pull the lever" kind of platformer puzzles, this is an interesting one.
No way did I finish all 100 levels.
