HyperRogue

HyperRogue is a unique casual strategy, whose main goal, traveling in a strange world to find a unique artifact called the Orb of Yendor. However, it is possible to deviate from the basic tasks and just traveling to collect various items or parts, of course, fearing all kinds of enemies. The game implements a variety of worlds, each of which is unique.
However, the main feature of HyperRogue is a unique realization of worlds, worlds created on the hyperbolic plane, consisting of six, and heptagons. But it used a system of non-Euclidean geometry, that is, the sum of all angles of triangles is always less than 180 degrees. In such a world, it is very difficult to go back or be in the same place twice. But the development of events always depends on the decisions you make.
