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

You watch your hero grow from weakling to god-slayer through incremental stat gains and automated fights.

What players say

Players are split on the game: some enjoy the incremental auto-battler loop, others find it too short and basic. The major complaint is class imbalance, with the assassin either being too weak to status-immune bosses or overpowered against them, depending on the reviewer. Completing all achievements requires replaying the same content with each class, which some find tedious.
