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 bright, cartoony 3D platformer where you run and jump through colorful voxel levels collecting as much as you can for a better grade.

What players say

Players praise the charming rat-themed 3D platformer for its cute art, varied level design, and secrets, but note some jank, hard-to-see boss attacks, and controller compatibility issues. The developer is described as responsive to launch problems.
