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.

What players say

Players split on this one. Many enjoy the gravity slingshot mechanic, comparing it to pinball or billiards in space, and find exploration relaxing. But others say the lack of tutorial and frequent escape failures make it frustrating, with rare resources and a buggy ship system trapping you on heavy planets.
