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 frantic dash to dodge a storm of projectiles while frantically scooping up coins against a ticking clock.

What players say

Players describe it as a simple, minimalist bullet hell that removes the shooting, leaving only dodging and coin collecting. The game is very short with just five levels, and while some find it rewarding to beat, others criticize its lack of ambition. Players are split on the difficulty, with some praising the challenge and others pointing to questionable hitboxes.
