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 nostalgic compilation of short, varied indie games that play like quick, casual challenges from the Flash era.

What players say

Players praise this as a faithful collection of classic flash games, especially the Protector and Arkandian series, that brings back fond memories of the Kongregate era. However, some criticize the single save slot and bugged achievements, while others note the games are harder than they remember.
