I don't know what that game looks like, but a lot of early 3D games have not aged well at all, and 2D games of the same era look much better than them today. I think it was only around late 1997 that 3D games surpassed 2D ones to the point that they hold up better today.
I was recently playing a bunch of fanmade levels for Lemmings (Mac version with 640x480 graphics) and the game still looks reasonably good, despite being from 1992. It doesn't have that ugly, blocky look that characterizes many early 3D games, especially from the Doom and Quake 1 eras.
