Sleepy Jack, the latest game from the developers of the acclaimed platformer Cordy, is now available for the iPhone.

Previously exclusive to Sony Ericsson's Xperia Play, Sleepy Jack sees you control the eponymous lad in a journey through his toddler subconscious.

As you fly through Jack's dreams and battle the twisted inhabitants of his bedroom toy box, you're armed with a toy ray gun to shoot down his nightmares.

It's a surreal shooter of sorts, then, and now that it's arrived on the iPhone, there's support for both Game Center and OpenFeint included to handle your achievements.

Sleepy Jack is available from the App Store for the discounted price of 99c.

It's a limited-time offer, so act fast if you're after a dreamy shooter without a nightmarish price tag.
