Don't Look Away: a candle-lit horror game where the GPU shader is the game.

Something is in the house. It only moves in the dark. Your cursor is a candle. While your light is on the Visitor, it stands still; look at the window, the portrait or the door, and it takes a step closer, in a new pose, somewhere new. In the dark you only see two pale points. When it reaches you, the candle goes out.

Features used: Rive CLI and GPU Canvas, plus Scripting, Data Binding and State Machines.

- GPU Canvas (WGSL): the darkness is a fragment shader: a breathing pool of candlelight around the pointer, smoke in the light, a vignette that closes in with dread, and a tear across the picture every time it steps.

- Rive CLI + RML: the room, the words, the view model and the state machine are plain markup, built and checked with rive --verify, inspect and headless screenshots; the demo video was rendered by replaying a scripted pointer frame by frame.

- Luau scripting: one rule, it only moves while the light misses its head and body; it also draws the Visitor and the candle in your hand.

- Data Binding: its distance drives the step counter and the portrait on the wall, which slowly becomes her. State machine: title, ending, and the flash of the scare.

- Rive Editor: the file was opened in the editor, and the claw marks beside the door were drawn there with the pen tool and pulled back with rive pull.

The cursor as a candle and a Visitor that moves only when you look away is a strong mechanic. How did you do the lighting in the shader?
