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

A playful isometric pixel adventure where you explore a retro-futuristic space station solving light puzzles and arcade challenges at a relaxed pace.

What players say

Players call it a charming, retro-style point-and-click with a silly story about a stinky cosmic sandwich and clean pixel art. The puzzles lean on moon logic and can be cryptic late in the game, yet most find the difficulty manageable due to few locations and fast interactions.
