Jack's Last Light 🎃
A jack-o'-lantern keeps watch over a foggy graveyard, and your cursor is a lantern. Move it to part the fog and find the ghosts drifting inside. Jack's eyes follow you everywhere and he leans in when you get close. Click him and a spirit possesses him: an evil laugh, a hellfire candle, a blood moon and a cursed CRT glitch. Click again to banish it. Every soul he claims is counted.
Features used: Rive CLI + GPU Canvas (both)
• Rive CLI: the whole scene is RML, written with a coding agent and checked with rive --verify, rive inspect and headless screenshot tests
• GPU Canvas: 4 WGSL shaders: a moonlit sky with a cratered moon, domain-warped fog with a cursor "lantern" hole, the candle flame clipped to Jack's carved face, and a CRT possession glitch
• Scripting (Luau): turns the pointer and clock into view-model data and drives every shader layer
• Data Binding: pupils, head tilt, candle flicker, ground glow, souls counter and the hover cursor
• State Machine: 5 layers (Possession, Notice, Ghosts, Bats, Wings); a click listener toggles possession with a negate converter, and an audio event plays the laugh
• Second pass: recarved Jack's face (scowling almond eyes, fanged grin) and added the possession laugh (CC0 sound by AntumDeluge)

The Haunted Client Feedback 👻
Every designer's real Halloween horror. A cute ghost client haunts a design approval screen. Each "Approve design" click summons new feedback ("make the logo bigger", "17 more colours", "use the first version"), and the design obeys each one while the screen gets possessed and the fog thickens. Lock the brief to finally get "Approved. Finally."… until the P.S.
Built with both the Rive CLI and GPU Canvas.
Rive CLI + RML: the whole scene was written by a coding agent in Rive Markup Language, with a live preview.
GPU Canvas: two WGSL shaders (drifting fog and an RGB-split possessed-screen glitch), driven by the state machine.
Scripting: Luau scripts run the shaders and make the ghost's eyes follow your cursor.
Data binding: a view model drives the feedback flow, the live "Round N of ∞" counter and cursor tracking.
State machines: 5 layers covering float, feedback, the design's reactions, button modes and the twist ending.

The Night Clerk
A haunted lost-and-found office. Open three drawers to recover your shadow, a borrowed heartbeat and a letter posted tomorrow. The ghost follows your pointer, rises when a drawer opens and reacts to each discovery.
Built with Rive CLI, editable RML vectors and text, Luau interactions, data binding and an original WGSL shader on GPU Canvas. The shader adds quiet drifting fog and a warmer glow when the clerk wakes. A default Rive state machine keeps the scene and bindings active.
Click or tap the drawers, or use keys 1, 2 and 3. R starts again; M reduces ambient motion. The 33-second walkthrough shows the working scene and a short excerpt from the actual RML source.
Original AI-assisted artwork, code and copy, created October 5, 2026 for this challenge. Font: Lora, used under the SIL Open Font License.
Halloween Hotel: a crooked Gothic hotel under a giant moon. Click the windows to catch 15 famous monsters mid-routine (Dracula shaving at a mirror with no reflection, the Mummy wrapping himself in toilet paper, the Grim Reaper working the front desk) and find them all before sunrise. Every set of three you finish plays a reward, and finding everyone finally lights up the NO VACANCY sign.
How it was built: I modeled and baked the hotel in Blender, and it runs as real-time 3D (140k triangles) inside Rive's GPU Canvas, with custom WGSL shaders for the sway, the shutters, the neon and the magic. Claude Code and the Rive CLI wrote the scene in RML and the logic in Luau, and checked their own work with --verify and headless screenshots. Data binding drives the guest cards, the tracker and the mobile layout, and state machines run the card, the welcome and the finale. After rive push, I refined it by hand in the Rive Editor.
Features used: Rive CLI + GPU Canvas, plus Scripting, Data Binding and State Machines.

Loved this! I found 14 out of 15. Maybe the flying witch was the 15th and I missed clicking on it. Don't ever remove this! Bookmarked forever!
