One in a long series of short animated Viper-style games centering around the blue-haired protagonist, Lime. This one is split into three "Areas" that you can do in any order, and is really more an animated story rather than a game with branching choices. It appears Anex86 will freeze on the disk transition, so you may wish to use another emulator.
A full English patch for all games in this series is available for download on this website.
