My First Boo! 👻
My First Boo! is a Halloween score-chasing game about an ink ghost scared of its own shadow.
Tap falling candy, avoid bats and webs, and tackle three stages with changing wind, tougher item patterns and a final-stage comeback chance. During bonus time, drag the lantern after the fleeing ghost. Grow its silhouette on the wall until it notices, freezes and jumps in fright to earn BOO! +300.
I built it with a coding agent using the Rive CLI, RML, Luau scripting, Data Binding and a State Machine. I paired Illustrator-prepared SVG layers with directional reflections, floating motion and expressive reactions to keep the ghost’s personality consistent.
A shared Supabase leaderboard compares players’ best runs. The 48-second walkthrough shows gameplay, actual RML excerpts and an Editor view of the layered artwork.

🎃 Can you beat Jack at darts? 🎯
🎮 Play here: START
This is my second game for the challenge, and honestly it was a totally different experience from the first one.
Last time I built everything by hand. This time I wanted to try the Rive CLI with Claude, and wow… I just described what I wanted in the terminal, and step by step a whole 3D darts game appeared. Jack, the dartboard, the castle room, all made with GPU Canvas shaders, no 3D models at all.
But not everything went smoothly 😅 AI really struggles to draw nice SVG icons and cards, so I opened the project in the Rive Editor and redesigned the cards, their icons and the button animations myself.
🎯 How to play
You play 5 rounds against Jack, a pumpkin-headed gentleman who really doesn't like losing.
Pull back to aim, release, and stop the meter in the green zone for a perfect throw.
Before every throw you pick one of 3 mystery Halloween cards 🃏 Some help you (Bat Swarm, Witch's Brew…), some are curses (Tombstone 😈). And yes, Jack gets cards too.
This was my first project like this and I enjoyed every minute of it. I still can't believe how easy it was to make a 3D game this way, and I already have ideas for the next ones 👀
Try it and tell me your score! 🎃👻
Delivery vs Zombies is my entry for the Rive Halloween Challenge with Contra. 🧟🍕
A one-level runner set in Buenos Aires on a full-moon night: Matilda has to deliver a pizza through a city full of zombies, with werewolves howling from the rooftops and fog rolling in, for an app that never stops rushing her. At the end, the app prints your receipt, with deductions.
Made from scratch over nine days for this challenge:
Rive CLI: the whole file written in RML from the terminal with Claude Code. 291 commits, checking every change with headless screenshots and pushing back and forth with the Editor.
GPU Canvas: a custom WGSL shader for film grain, chromatic aberration and lens blur, tuned to hold 60 fps.
Scripting for the game loop and physics, Data Binding to dress every zombie at random, State Machines for characters and UI.
The agent was fast, but its art came out generic. So it blocked out the shapes, and I redrew, rigged and animated everything by hand in the Rive Editor, adapting Vero Beltrán's original characters so they read from far away. Matilda squashes on every landing, the zombie bite runs 52 frames, your scooter parts stay where you got caught, and the receipt prints line by line. The UI comes from a design system I built in Claude Design. Original chiptune music.
Playtested with friends until the jumps felt right. English and Spanish, effects and audio can be switched on and off while you play. Desktop only for now.
Let me know if you make the delivery on time. 😅
LIGHTS OUT 🎃👻
A Halloween arcade game where you're the ghost who puts out the street.
Slip into a charred pumpkin, grow a body of roots and then stomp, punch and slam all the lights. Last light out… and the portal opens.
Play with sound here (works on mobile too): https://lightsout.luxlui.com
I've always wanted to make real games, and Rive finally lets me. I drew the characters and the street, built my own Claude Code system to direct a team of agents, judged every round and finished it by hand. And it was so much fun. This is just the start and I'm still learning.
How I built it:
• Rive CLI: character, 3D world and intro written in RML, signed and bound to editor files
• GPU Canvas (WGSL): a 3D street with 21 lights, night, volumetric light and bloom, a flame-lit 3D pumpkin head, fog body, punch fire
• Luau scripting: live kinematics, Rubberhose limbs, 3D projection of every joint
• Data binding: one Game view model across three files and the page
• State machines: possession, actions (stomp, punch, giant fist, burn-out), the intro
• Audio: the master's voice (ElevenLabs) and effects inside the files
• Rive Editor: faces, actions and intro finished by hand
