While it is interesting, Super Pac-Man felt more like it should've been more of a bonus round in Pac-Man instead of a full-blown game.
Instead of standard pellets, you're in pursuit of keys that unlock openings to various items like bananas, apples, eggs (sunny side up), and the power ups.
You still have the traditional power pellets that allow you to gobble up ghosts, but in Super Pac-Man you also have a super pellet that increases the size of the player. This pellet allows you to go through/fly over the ghosts... while you track down the keys.
The objective remains the same in with the chase or be chased gameplay, you just have to get all of the items instead but... it really feels like it should've been a bonus round that gives you a break from the standard Pac-Man stages.
