I don't know [1], but!... When you reduce things down to a minimum amount of essential detail, things tend to look similar to other things that share the same constraints. I noticed this when researching Mondrian and the De Stijl (neoplasticism) art movement -- they restricted their palette to mostly primary colors. I could ask if Google's logo or the colors in a bucket of LEGO bricks were inspired by Mondrian directly, but another possibility is that the neoplasticists discovered some kind of minimal, universal design pattern that feels timeless and likely to be "rediscovered" again and again. Are Monument Valley, MagicaVoxel (and Minecraft) inspired by Escher, or is it a natural coincidence that comes out of the minimal use of geometry and perspective they all employ?
[1] Edit: I did some more digging... Looks like they used Unity to create Monument Valley: https://unity3d.com/showcase/case-stories/monument-valley
