HyperRogue has 352 reviews. It is a rogue like that is played on a hyperbolic plane rather than a euclidian one.
If you're not familiar with hyperbolic geometry, don't be fooled by the videos. It has the illusion of looking like it is on a sphere in many of the videos. It's not! Also, you don't need to be some master of hyperbolic geometry to play. I don't really understand it but can still play the game well enough.
Essentially, imagine a hexagonal grid. Now, replace some of those hexagons with septagons (7 sided). The further away you get from a point there will be way more tiles in the hyperbolic grid than the euclidian.
The UI is pretty bad, the menus are pretty icky. Those are my only real complaints.
The game is charming. It has.a very retro feel to it. The music reminds me of something of hear from an old school point and click game or RuneScape. The graphics are minimal but charming.
The mechanics are easy enough. You get hit and you die. Most enemies die in one hit. There are no weapons or stats. It's more like chess in a way. The game will also not let you accidentally move somewhere you'd die, so, yes, very much like chess with checkmates.
Because the game is so simplistic you can get into a flow state where you quickly move and attack enemies. It's very satisfying to play.
