Good point, the movement is more isomorphic with a fully spherical 2D geometry game than I was thinking. But I still wouldn't say it qualifies as non-euclidean in the same sense as hyperrogue at all, given that you aren't fully stuck on a sphere (and they don't give any way to change the view to a top down 2D spherical geometry view; because it's actually just a regular 3D game).
More relevantly to your original comment, it is always going to be far easier to understand 2D spherical geometry (possible to create in 3 dimensions, we see it every day) than 2D hyperbolic geometry (not possible to create in 3 dimensions, completely foreign to us), so I don't think it is a 'display' issue at all.
