“This game is a flawed gem. I cannot recommend it in a world where Sunless Skies and Space Rangers 2 exist. Pros: * Atmospheric writing * Ironman mode brings tension and weight to every decision * Feeling of crawling…”
“6.5/10 + deep lore and good writing + simple, but fitting visual - slow, draining gameplay - schizophrenic identity comment: i gave it several attempts, but my interest in the lore failed to overcome the tedious…”
“Good story, choices matter, the scary dark fog is scary and crabs are big. Also, I am allergic to shellfish, so this was extra scary. Great game 10/10.”

“Are you into Intriguing Snippets? Perhaps some Secrets? Well, then, how about a few Extraordinary Implications, Searing Enigmas, and one Dread Surmise? All jokes aside, this is an extremely well-written game of weird…”

“Still haven't "beaten" it. A very unique roguelite, simple mechanics with surprising depth. I can't help but get lost in the atmosphere, trying to explore deeper into the dark expanse and discover what is hiding where I…”
“Great text based adventure game - I played a lot in between classes in university, since it's so easy to pick up or put down and jump back into it”

“I don't hesitate to say that this game is my favorite game of all time. Fair warning, there is a LOT of reading (which I love!), and even with all that text it still manages to put incredible amount of care into every…”

“It's tricky to recommend this game. It's painfully slow, and hard. The moment-to-moment gameplay is, truth be told, pretty mind-numbing. It's intentionally esoteric and obtuse-- which the game usually plays as a strength, but this also makes your early hours feel directionless…”
— a player, Steam review · 218 hrs played“A game with truly immaculate vibes. Never before have I felt so transported so suddenly into a world that is both intensely real and unfathomably alien. Though minimal in complex mechanics and skill based gameplay, it offers up an incredibly deep and fascinating world to…”
— a player, Steam review · 36 hrs played“It's a roguelike game that encourages exploration and then punishes you harshly for it. You can lose 20 hours of gameplay on a Captain on one bad roll. And then you get to start it all over again, from zero. And oh god does it hurt to start from zero. You'll be back to running…”
