HyperRogue

HyperRogue is a turn-based game in which the player controls one character exploring a world based on hyperbolic geometry, with cells arranged as a truncated order-7 triangular tiling by default (with a few exceptions). The player can also choose to play on some other tilings and honeycombs in two and three dimensions, in all eight Thurston geometries, along with a variety of quotient spaces. It borrows procedural generation and permadeath from the roguelike genre, and puzzle-based combat of Deadly Rooms of Death.

The world consists of 72 lands, each of which has a different theme, treasure, enemies, mechanics, and a magical power; the lands are usually separated by hyperbolic straight lines ("Great Walls") and change as one travels, thus allowing monsters and magical powers to interact between the different lands. The world is procedurally generated on the fly; some of the lands must be unlocked by fulfilling a prerequisite in the given play (e.g., collecting a certain number of treasures).

HyperRogue was called "one of the most interesting roguelikes to come around lately" in the book Exploring Roguelike Games. Pocket Tactics stated that it was reminiscent of Roger Zelazny's Chronicles of Amber series.
