A few years ago I made a pac-man clone with unity for android where the only difference was that you controled Pac-man with your left thumb and Ms Pac-man with your right thumb, called Pac-men if I recall correctly, it was a bit frustating but the innovative mechanics was a bit of fun by itself, both could eat ghost when powered-up, the ghosts movement logic was the classic one too (so it only took into account one the first pac-man to chose paths), not much later it was taken down from the play store for trademark infrigement, in my naiveness I assumed nobody care about such thing due beign such an old game and forgot to check beforehand, boy was I wrong. I considered changed the sprites and release again with a different name/ip but lazyness took the best of me, probably wouldn't have catched anybodys atentton with some other name anyway.
