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 cryptic 2D action game with pixel graphics where you explore a monochrome world, solving fragmented mysteries and managing self-damage mechanics.

What players say
Players describe the game as a free Yume Nikki-inspired horror platformer with a strong creepy atmosphere. The lack of English is not a barrier, but the controls can feel janky and some bosses are very hard. Exploring black-and-white levels without a map is a key part of the experience.
