This game is rated all ages. This game is intended for all ages. "It may not be the most fast-paced or engaging tale on the market, but it provides a distinct experience. Those looking to dive into a new yuri game can expect to swim with SeaBed for ten to twenty hours as they uncover its secrets."
"If what’s said so far – regarding the slow pacing and slice-of-life feel - hasn’t chased you off yet, SeaBed is overwhelmingly worth the purchase and is a nice, substantial read you can enjoy multiple times."
"Playing SeaBed was one of my most rewarding experiences this year and I’ve had a lot of rewarding media experiences this year. The game is 15-25 hours long and absolutely outstanding to those it’ll appeal to."
SeaBed is a yuri-themed mystery visual novel told through the perspectives of three separate characters: Mizuno Sachiko, a designer plagued by hallucinations of her past lover; Narasaki Hibiki, Sachiko's friend and a psychiatrist researching the workings of human memories; and Takako, Sachiko's former lover who has been rapidly forgetting her past, including how or why the two women drifted apart despite being together since childhood.
All three live in different worlds, but seek the same goal. To separate truth from illusion. To make sense of their own lives.
