In the enchanted underwater City of Glass, what will you sacrifice for immortality? Love, memories, freedom? Will you take freedom from others to win your heart's desire? Dive into a world of mermaids, mermen, and other merfolk, where every character has secrets, and nothing is what it seems!

"The Sea Eternal" is an epic interactive fantasy novel by Lynnea Glasser, author of "Creatures Such as We" and "Coloratura," winner of the 2013 Interactive Fiction Competition and numerous XYZZY awards. Your choices control the story. It's entirely text-based--283,000 words, without graphics or sound effects--and fueled by the vast, unstoppable power of your imagination.

The whales have granted the merfolk eternal life, and asked you for so little in return. Defense against the giant squid. Secrecy from humans. But when a rogue mermaid tries to destroy the gift of immortality, ancient secrets rise from the depths, and the delicate balance of society rests in your hands.

Will you fight to protect your immortality, or surrender it for a higher cause? Will you choose sides in the neverending war between the whales and the giant squid? Will your undying love save the City of Glass, or destroy it?

this review probably has spoilers but


i don’t really see the problem some people had with the diversity? i mean, Tamru being black and Faye being trans just made the story more inclusive and, no, the author wasn’t shoving their political views down your throats. for me, the idea that Tamru was getting hate when he was human for being black just showed how long he had been an immortal for.

<okay here come the spoilers>

the ending i got was that Tamru and i went back to the land. it was such a sweet ending that i couldn’t bring myself to replay to see each different ending (but i probably will later). it felt short for me but that was most likely because there was so much else that i skipped to achieve this ending.

<okay spoiler’s over>

thank you, author, for writing this. i really enjoyed it.

I Really Wanted to Like It, But. . .


I really wanted to like this game as it had a very intriguing premise, but it really gets too bogged down in being an author filibuster with their "message".

This game is called a "choice" game for a reason, but there were many situations wherein I was unable to express my real feelings (and therefore 'choice') on how to respond to a matter, which quickly destroyed any sense of immersion this game had for me.

I get it, the author wanted to tackle racial/gender/etc. matters in this game, but it came through in such a ham-fisted manner that this ended up reading less like an interactive story and more like a railroaded author tract.

CoG is starting to disappoint.


After years of some cool games, it seems as though CoG’s once benign gender neutral policy for its stories is morphing into something malignant. This story felt like a screed on the author’s own sociopolitical views. The politics were unavoidable but what was far worse was that the story was just bad.

Give it a pass. Check out Choice of Robots, Alexandria, or Choice by Gaslight for stories that have a sociopolitical view...but tell a good story along the way.
