Noobow is a Game Boy game released in Japan. Without more information, the exact genre is difficult to pinpoint.  It may be an action game, a puzzle game, or another genre altogether.  It likely features 8-bit graphics and simple gameplay typical of Game Boy titles from that era. This suggests it is a more niche title and possibly less well-known outside of Japan.
