This game is a touhou fan-game.
Reimu Hakurei is summoned to the Dream World in her sleep. Doremy Sweet appears and reveals that Gensokyo is facing a grave danger. The very space of Gensokyo has become distorted and chaotic, affecting even the Dream World.
Paths stretch out infinitely, logic of distance shattered, people get lost and trapped in an underground labyrinth. The kappa engineer Nitori Kawashiro identifies this phenomenon as "Hyperbolic Geometry"...
Deep within this mathematical maze, a spotlight clicks on. It appears that this spatial anomaly is not just a disaster, but a stage set for a grand performance...
