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 low-effort strategic loop of watching towers automatically fire at waves of cubes, with upgrades adding a steady sense of progression.
