We all oughta know Sqrxz by now. Sqrxz is a cool platform/puzzle game. It's a port of the TI-86 version. The port's just like the original (with some extra scrolling because of the smaller screen) just a lot slower. Too bad, for it removes some action from the game. Remember to set it at fast. The game's still nearly as cool, but a bit large for an 83.
