The 3D catalog: game boxes on wooden shelves, with the cat sitting at the counter next to its greeting.

The catalog in 3D

The same catalog has a room you can walk around in. The cat behind the counter is the AI Catbot, and they pick real games from it when you tell them what you feel like playing. Nothing is for sale, here or in there. Go in from here and this game is already out on the counter, with more like it waiting on the shelf next to it.

How it feels

You pilot a creaky Soviet submarine through the deep ocean with a pervasive sense of loneliness and creeping dread as you uncover a forgotten mystery.

What players say

Players compare Dark Sea to Iron Lung but say it is longer and has actual puzzles. They praise the claustrophobic atmosphere and the interactive sub systems, though some hit crashes from flare spamming. The learning curve is steep without a tutorial, especially for non-English speakers, and reviews split on whether the content justifies the low price.
