The cramped maze isn't the problem. The lack of intermissions isn't the problem. Hearing the intro tune several times during the game isn't the problem. Even the simplified, flickery graphics aren't the problem. The problem is the slippery control and very liberal collision detection that makes it very hard to tell where Pac-Man is going, and what he might run into along the way. Still, the game is consistent with its rules, if not exactly intuitive. Just about every other home version of Pac-Man plays better, even the official Atari 2600 version, but at least this game feels like Pac-Man, which the 2600 port can't claim. So that's something.
