Get ready to push your friends over in Whale Trail dev's new real-world Papa Quash game

It's taken an unusually long time for a developer to take the basic principles of experimental PS Move game J.S. Joust and apply it to iOS, but if there was going to be one crazy enough to do it, then it had to be Whale Trail creator ustwo.

In the company's latest game, Papa Quash (available for free with optional IAPs), you and an "unlimited" number of friends attempt to keep your iPhones steady to stay alive. Should you make too fierce a movement, you lose a life.

It sounds ridiculously boring until you factor in the 'friends' part.

Everyone is free to do what he likes to tip the scales in his favour - the winner is merely the one that keeps the phone balanced the longest. So, pushing, pulling, and other unsavoury activities are positively encouraged.

Papa Quash is out now for iPhone for free, and you can download it by hitting the button below.
