I don't know how I came across this, but I want it! Understanding higher dimensions has always seemed interesting. I've just never felt like I had the time to learn the math. I love examples that try to illustrate higher dimensions in the context of lower dimensions. The book Flatland is a good one. (Old and free on iBooks and possibly elsewhere. https://itun.es/ca/kvvUD.l ) Another example I like is the explanation of why a wormhole is a sphere in the film Interstellar.
I hope this game makes it to production.
