    Ik

    Ik

    It's a game based on a puzzle survive sistem.

    The game tells us the story of Ik, a mayan young man. As we know, the entire Mayan Civilization disappears in some point back in time, but actually they went to another place, a better one (Something like " In a galaxy far far away"). The problem? Well, Ik didn't make it, he was left behind. So, abandoned in this world, he found Ok, the stone dog (I know, the names are little confused because they are based on Mayan Language). So, Ok tells our hero that he has to climb the Tower of Challenge to reach the other wolrd, where his people is. That's when the game begins.
