Hyperrogue is a roguelike set in hyperbolic space: https://store.steampowered.com/app/342610/HyperRogue/

And the author has a lot of videos on non-euclidean spaces! https://www.youtube.com/@ZenoRogue

There's also Hyperbolica: https://store.steampowered.com/app/1256230/Hyperbolica/

And that author also has a lot of videos on its development, non-euclidean spaces, and other games that play with space: https://www.youtube.com/@CodeParade

Not quite in the same family, but maybe a distant cousin - a game where the speed of light is so slow, that merely walking around causes you to experience relativistic effects: http://gamelab.mit.edu/games/a-slower-speed-of-light/
