Yokus Island Express is an adventure that blends pinball with open-world platforming, starring Yoku, a dung beetle who takes over as postmaster of Mokumana Island.

Rolling his ball across the island, Yoku is launched by flippers and bumpers to reach new areas, deliver mail, and help the local residents with their problems. The island opens up gradually as new abilities are earned, in the manner of a Metroidvania. Its hand-painted visuals and inventive mix of genres give it a character all its own.
