Orisuji is a turn-based maze puzzle designed for iPhone Duo. Unfolded, the phone is a book: a paper maze on the right page, a second sheet with holes on the left. Fold it and the two pages become one maze on the cover screen. Unfold it and the left page lifts away, carrying whoever stood on it. 69 levels in six worlds, with a red crane, two cats, a fox and a gold-leaf moon. It plays on every iPhone and iPad too. $4.99, no ads, no in-app purchases.
