Crytek, the developers behind blockbuster games such as Crysis and Far Cry, have released their first game for the iPhone.

It's called Fibble, and it has you flicking and rolling your tubby alien protagonist around a host of levels.

Although there's considerably less alien genocide here than you'd find in traditional Crytek fare, this cutesy physics-puzzler is an intriguing proposition.

After his tiny spaceship crash lands in a family home, Fibble finds himself alone. To return home safely, he'll need to reassemble his crew - and that means exploring this strange new environment.

Fortunately, Fibble's crew is a skilled bunch. And once found, they'll be able to help you navigate this alien abode, for they each possess unique powers.

Vroom can give you a bit of a speed boost, for instance, while your ole buddy Byte can help you reach new heights in a level.

Fibble is available now, priced at $1.99 for 30 levels of physics-based fun.
