Jade Cocoon: Story of the Tamamayu is a role-playing video game developed by Genki exclusively for PlayStation.
The game combines elements of role-playing video games and virtual pet management.
It was developed by Genki in collaboration with Katsuya Kondō, character designer for the Studio Ghibli movies Kiki's Delivery Service and I Can Hear the Sea.
Jade Cocoon is the story of Levant, a young man who lives in the town of Syrus. The silent protagonist is guided by the player on his quest to follow in his presumably dead father's footsteps to become a Cocoon Master. To do this, he must marry a Na'gi woman, and is betrothed to a girl named Mahbu.
On the day of a large festival in Syrus, the village is attacked by demons known as the Onibubu, which cause many villagers to fall into a deep slumber. An elderly Nagi woman, Garai, repels the Onibubu using Nagi magic before their curse affects everyone.
Reviews of Jade Cocoon praised its graphics, including the game's FMV anime cut-scenes and environment—which consisted of over 600 pre-rendered backgrounds—as well as its audio, sound effects, and simple interface.
The game's deep monster breeding and merging system was also well regarded. However, the game was considered short alongside other RPGs of the time with a story of only 15 to 20 hours. Jade Cocoon was criticized for the inability to fight alongside monsters, and its Silent Hill-style control scheme, which makes it difficult to avoid battles with some monsters.
One of the most unique RPGs on PlayStation's catalogue.
