Many players complained that the game is too hard, harder than PacMan. The thing is, there's nothing in common with the PacMan apart from similarly looking characters and the fact that there is a maze and fruits you collect, but everything else is original not present in any other game. And this game do require you to think and trick other characters. First you need to figure out how they behave and then come up with the strategy. The game is quite easy actually, once you get the hang of it.
Look at the video below to see just how simple it is. Game can be played with either keyboard, mouse or touchscreen.
