Now you have to be asking yourself that's an interesting title of a game, I'm assuming its a game, and you would assume correctly. Klonk Games in partnership with Deck13 gives the world, or at least those using Steam (Green Man Gaming or Humble Bundle), Xbox Ones, and in March the PlayStation 4.
You will be playing as one of two characters, playing with friends helps increase the awesomeness. These two characters have a strange bond between them where they can switch size with one another. You can become big, or you can become small. Each of these have their advantages and disadvantages, hence why you need to work as a team.
You will be tasked to get through 40+ levels of co-op, or 30 levels of single player. If you do the co-op route you have the choice of hot seat or online. The game is set at $14.99, and if the trailer is any indication of what you're getting, I think $14.99 is going to be just the right amount.
