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 straightforward arcade shooter that feels like feeding quarters into a classic cabinet, with clean minimal visuals and snappy action.

What players say

Players praise the addictive core loop, smooth controls, and the soundtrack that fits the retro vibe. Many enjoy the high number of ship part combinations. Some feel the random upgrade system can make runs feel unfair, and a few reviewers note the game starts to feel repetitive and wish for more enemy variety.
