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.

About

Sonic the Hedgehog: Borderline is a ROM hack of the original 1991 Sonic the Hedgehog for the Sega Genesis. The project reimagines South Island through a narrative set after the events of Sonic Mania Plus, where Dr. Robotnik uses a portal and the Chaos Emeralds to build "Robotnik Land," a machine threatening to awaken an ancient monster in the Earth's core.
