It's just pac-man. If you like pac-man, get it. If you don't, well don't. Nothing really to see here.
I mean, it's just Pac-man.
I quite like Pac-man myself, so if you do it's easy to recommend.
But it's pac-man. If you don't like pac-man, pac-man won't change your mind on it.
I never played any of the originals, so I couldn't speak on whether it's a good emulation or not. So uhh... Anyway.. It's pac-man.
If you've been living under a rock. Your pac-man.
And you go around eating dots. And pills.
And occasionally fruits and ghosts.
For points.
Theres leaderboards and stuff, if thats your thing - to see where you stack up against the rest of the world in pac-man and theres some achivements to plow through, if thats your thing.
Otherwise, yeah. It's pac-man.
