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 praise the FMV story and surprising plot twist, but warn the gameplay is a simple tank-control shooter with horizontal-only movement and 60-second survival rounds. It is very short, about 60 to 90 minutes, and reviewers split on whether the clunky mechanics are part of the charm or a limitation.
