Use your head to break some blocks, move others, while a few enemies try to be annoying to avoid you from solving the many platform puzzles which form this game.
It seems the main character, a walking moai, an Easter Island statue, goes in search of smaller ones with some kind of relation to it. But well, as if one cares with this kind of game, the only impact it have is that you should get them to finish the level, so each one always is the same, but not in the same way. Start somewhere around the place, make your way to them and then reach the big doors to finish the level.
