Forget-Me-Not is an impressive retro game. It's like Pac-Man, but that's just a way of characterizing the mechanics rather than the actual gameplay. Essentially, you run a little guy around a random Pac-Man style map, but instead of just eating pellets, you're also shooting and trying to collect a key that will eventually lead you out of each level. There are "ghosts" chasing you, but you can shoot them down or "grind" on the walls to build up some power and take them out. Charged up "ghosts" can also explode, which can actually change the shape and layout of the little map.
The little retro bleeps and bloops and simple graphics make the experience enjoyable and simple, at least until you get to the really big maps and things get chaotic. There are three different modes, Game Center integration and a "multiplayer" mode where two people can play the same game on the same screen. Forget-Me-Not is currently US$1.99 for a universal version. It's definitely a must-see title, especially for fans of retro-styled games.
