On the face of it, Headspin: Storybook is basically a ‘Spot The Differences’ game, but the way it is all presented is rather lovely.
Provided with an open book, all the pop-up on the right-hand page must be the exact mirror image of the left-hand page to progress. There’s a time limit involved, of course, and clicking each object will make it spin and face the opposite direction.
It’s lovingly illustrated and the calming music really adds to it. It also gets extremely confusing in later levels as you scour the scene trying to find all the pieces that need spinning as quickly as possible.
Give it a play at State of Play.
