Your English is great! Though probably it would be better to ask this on the page of HyperRogue, as it is confusing and harder to find that way :)
Regarding inspirations, well, I have always been interested in both mathematics and game design, so naturally I wanted to create a game in non-Euclidean geometry. I have written a series of blogposts about all the inspirations of HyperRogue: http://zenorogue.blogspot.com/search/label/sources (I must update it...). Thanks, we are planning to keep working on it :)
I have collected cool games and simulations are in the "geometry" link I have posted above.
