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 colorful, emotion-driven adventure where you channel distinct feelings like anxiety and happiness into special powers.

What players say

Players consistently praise the emotion-switching mechanic and the hand-drawn look, and most find the hard difficulty genuinely challenging in the later stages. A recurring complaint is the imprecise movement, with keyboard controls feeling slippery and wall jumps unreliable. Some say the puzzles become repetitive and lose their pull, while others finish all 10-hour runs happily.
