Based on "Keroro Gunso" (known in Korea under the character's local name), the game offers the classic mechanic of spotting differences between two nearly identical images populated by the series' cast, in an edition designed specifically for the Korean audience.
It's an example of how the most popular anime licenses generated local versions adapted to specific markets, in this case with a simple puzzle mechanic accessible to all ages. Its circulation outside Korea was practically nonexistent.
