Quirky iPhone title Doodle Jump has notched up sales in excess of four million according to its co-creator Igor Pusenjak of development studio Lima Sky.

The game is priced $0.99/£0.59.

"Those are all paid downloads as there never was a 'lite' free version and Doodle Jump never had a 'free for a day' or similar promotions," Pusenjak told Kotaku.

Doodle Jump was released in the autumn of 2009.
