I couldn't find any  with significant coverage of this game either.  However, it is possible the game was more notable in Japan than in North America.  Using the game's Japanese title (ラジカル ラジアル) as a Google search term yields a bunch of results.  Unfortunately I don't read Japanese and have no idea what Japanese gaming sites are considered reliable.  But it might be something for someone familiar with the language to investigate
