There’s another game being developed in a semi-3D hyperbolic geometry called Hyperbolica. The dev makes some fantastic videos [1].

The point about rendering hyperbolic 2D using the Poincare embedding is that you see more of the game world, but what is "closest" is larger, somewhat like POV 3D but unlike traditional roguelikes.

John Lamping invented a file browser based on hyperbolic 2D [1,2].

At the first encounter I find this game very aesthetically pleasing and groundbreaking in an original dimension. I see it's been around for a while but I missed it before. I personally am a bit saturated with the mainstream 3d game mechanics, somehow 2d games captivate me more.

Cool! That inspired me to try to generate such a rendering myself, but googling it is not as easy as it seems. Sure, there is an article on Wikipedia about "https://en.wikipedia.org/wiki/Order-6_hexagonal_tiling", about a "regular tiling of the hyperbolic plane" with hexagons, but the hexagons themselves in that tiling aren't regular...

EDIT: that might be because they're not hexagons, they're heptagons (https://en.wikipedia.org/wiki/Heptagonal_tiling). Duh...

I'm curious, how would you store data about the maps of these worlds? Is there a certain format that's needed? I imagine it couldn't just be a 2D array, or if so, it would need to be a lot larger than a normal map and you wouldn't check all cells.

For some reason this reminds me of All Mimsy Were the Borogroves.

Some kids find a set of four dimensional educational toys, and figure them out.

This reminds me of DROD (1996)

I'm a roguelike enthusiast who's attempted to play HyperRogue many times but always get stuck on not understanding the geometry at all. Any tips from those who have?

Bought and played. It’s ok. Monument Valley still remains my most favorite.

It's like Rogue played inside a Mandelbrot fractal.

Is there a tunneller version?
