Monument Valley 2’ s UI is a beautifully illustrative puzzle box all on its own, chirruping and chiming as you spin it around to browse levels. You’re even given power over its design. At the end of each chapter is a chance to create your own ‘sacred geometry’ drawing to encircle that level in the menu. Slide your finger around a central point and Ro conjures perfect mathematical snowflake shapes according to your movements. It’s as oddly soothing to mess about with as the Spirograph toys that so clearly inspired it.
