Nini also praised its responsive controls, animations, customizable options and audio, but saw the occasional sprite flickering and issues with collision detection as negative points.

[24] Mega Fun's Martin Weidner agreed, lauding its technical performance for pushing the Game Gear's limit, audiovisual presentation, "exemplary" playability, sophisticated weapon system and well thoughtout stage design.

[25] Consoles +' Marc Menier disagreed with Nini and Weidner, finding the overall presentation unremarkable and criticizing the inconsistent visuals, "insipid" music, use of unlimited continues and collision detection issues.

[26] HobbyConsolas' Antonio "Boke" Caravaca praised the colorful visuals, enemy variety, sound effects, controls, diversity of weapons and items, as well as the multiple difficulty levels, calling it "The best shooter appeared for Sega's handheld."
