Jungle Wars 2: Kodai Mahou Atimos no Nazo

Jungle Wars 2: Kodai Mahou Atimos no Nazo ("Jungle Wars 2: The Mysteries of the Ancient Magic Atimos") is an RPG from Atelier Double and a sequel to their Game Boy RPG Jungle Wars. The game was never released outside of Japan. The protagonist and his friends are all hyper-intelligent animals of various species. Though the world appears to set in prehistoric times, there are actually many anachronistic elements which are played for comedy. The game is also notable for its day/night cycle, and the various subtle changes that would happen to the world whenever the sun rose or set.
