Yoshi and the Mysterious Book

Yoshi and the Mysterious Book plays on the Mac at 60 fps, the game's own rate. Tested from a new save through the opening movie, Mr. E's dialogue, Chapter 1's page and the first habitat, with walking, jumping and the flower friend, then ending an exploration, saving and loading that save. No iPhone or iPad app has been built yet.

How it runs

In the first habitat on an M6 Mac with 16 GB, the median frame time is 16.7 ms, with most frames under 17.1 ms, and the game uses about half of one processor core. An occasional frame takes 65 to 79 ms. The pause menu's blurred background shows correctly, and the water on Chapter 1's page has its colour and foam.

Memory is tight: the first habitat leaves about 0.6 GB of the game's memory space free, and later chapters have not been measured, so they may run out. Another tester reports that the first level and part of the second work, with error reports on the second level that the project developers have not checked themselves.

Bring update 1.0.2

Tested with update 1.0.2 (v131072; the title screen shows Ver. 1.0.2). The game is packed from a single .nup file of 41 GB that holds the base game and the update.

Controls

The Packed app starts in the 3D touch layout, because the game is a 3D field and uses both triggers.

• From an empty save, press A at the title and A on New Game. Press Plus, then hold Plus for about two seconds, to skip the opening movie, and press A through the dialogue.
• The magnifier is on the left stick; put it on the flower and press A to enter the first habitat.
• In a habitat, the left stick walks and A jumps. To end an exploration, press Plus, move down to End Exploration and press A.

Good to know

• The game saves only when an exploration ends. Until then, a restart shows New Game again; after it, Start Game continues at Chapter 1's page.
