The Last Lantern - a full 3D Halloween game, built and running entirely inside one Rive file.

The candle is dying, and the graveyard is not empty. You wander a haunted graveyard in first person with a lantern, catch ghosts in your light, bring their souls to five jack-o'-lanterns to relight them, and survive the red-eyed wraith until you reach the church, before your candle burns out.

How it's built😍 - Rive CLI + coding agent: I directed my coding agent through the Rive CLI. It wrote the RML scene, the Luau game scripts and the WGSL shaders, verified every build with rive --verify, captured test frames headless and pushed straight to my Rive file. I played every build and steered each iteration (controls, difficulty, fog, the scare).

- GPU Canvas: the whole 3D world is drawn in real time with custom WGSL shaders: moonlight shadow map, triplanar textures, wind bending the dead trees, volumetric ground fog lit by the lantern and the moon, 4x MSAA and a filmic post pass.

- Scripting: Luau runs the game: first-person movement and collisions, ghost and wraith AI, soul capture, candle wax, havens, tutorial, sound, dawn ending.

- Data Binding: a view model drives the HUD (souls, lanterns, candle), the title, game-over and dawn screens, tutorial hints and keyboard input.

- State Machines: screen transitions and UI animations.

- Human touch in the Rive Editor: I reworked the title screen by hand (colors, title, How to Play layout).

- Blender: I modeled the graveyard (about 185,000 triangles), exported as a binary mesh the shaders draw directly.

Controls: hold the mouse to walk, move it left or right to turn, click a ghost to catch it, press FLARE to drive the wraith away. Arrow keys work too.
