Zool on Game Boy is interesting mainly through contrast with its Amiga incarnation, Gremlin's flagship 16-bit micro mascot that this handheld port struggles to live up to. The title stayed under the radar on the US market, with no reissue and little critical recognition, which explains its thin circulation. Collector appeal rests on the wider Zool licence and its alien-ninja mascot rather than the game itself, sought by fans tracking the character across every platform.
