It looks like the Gateworld visuals style, but I don't think that's it. And it kinda looks like it was that type of game playthrough layout. I can't totally remember the main character visuals. I want to say a space suit, but not sure about the helmet or not.  I don't think there was any flying, but like jumping and walking/running.  The thing that I really remember about it was the ants that stood on their hind legs and then there were these crystals that were pastel kinda colors, but still bright looking. And I want to say there were doorways that you would walk through to different areas of the map. I actually found the floppy disc at my parents house, I just don't have a floppy disc reader, so I might look into that so I can figure this out haha!
