Erehwon

In this game, you play a young person who wants to be friends with the town's cool kid and his friends. However, to play his game, you need dice. Five dice. As you go on a search for them, things begin to get weird.

This game incorporates a number of concepts in geometry and topology, such as the Klein bottle (a surface with no inside or outside, which also was featured in Trinity); platonic solids (the five solid shapes which are as symmetric as possible); duality (where vertices and faces of a shape are swapped); Hamiltonian circuits (where you walk through every vertex of a graph without repetition); connected sums (which amounts to wormholes in physics); and a few other references such as the equations for quaternions.

A lot of this amounts to an extended in-joke, but otherwise the game is fairly well put-together. I feel that it would have benefited from some more explanations, such as an in-game textbook.
