Beltramia: The Nearer Horizon

A self-contained portrait-first hyperbolic navigation puzzle. The player always occupies the visual center of a Poincare disk. Choosing one adjacent room applies a disk-preserving Möbius transformation to all thirty-seven canonical room coordinates, so the destination becomes the new center while the complete archive contracts and expands around it.
