Inspiration

I was first inspired by feedback I got from Pixel Fun 2001. The card buying system was confusing and slowed things down. I noticed that random visitors in my world didn’t have the patience to figure out the game, and preferred the platforming and exploration areas.

This led to the rebrand: RULE BREAKERS MUST DANCE - a new hook where unauthorized fun lands you in disco jail. While Wacky Word Matchers is ‘authorized fun’, it’s up to you to find out what’s unauthorized. I was inspired by a ridiculous moment at a cyberpunk festival where a friend and I had to do 5 minutes of time in a laser jail. I wanted to bring this humor into my world.

What it does

RULE BREAKERS MUST DANCE is a party card game reimagined around the idea that fun is illegal. Players now get a fresh hand of cards each round, with no grinding or menus - just instant, replayable fun. A pixel reward system allows players to simply unlock expansion packs, and hundred of new cards keep things fresh.

To support new and solo players, two funny NPCs deliver onboarding as a scripted show, blending AI and voice acting with deadpan camera movement. Every round ends in a celebration with the winning card displayed and everyone dancing.

The world’s lore is driven by Joy Control, a fictional surveillance agency that punishes fun with a trip to disco jail, complete with frog guards, confession stages, and custom music. Using Horizon’s Camera API, players can monitor others and trigger world events, from jail sentences to splash zones. The disco jail and joy control areas are both completely new.

Other features include:

  • A typable, interactive keyboard with physics and particles
  • A bug-squishing minigame for early decision-makers
  • A quiet lounge for players to chat
  • Platforming zones, including one that climbs to the top of the computer
  • A daily scoreboard photo booth
  • A cinematic voting station for Fun vs Law & Order

How we built it

First, I simplified the core game loop. I replaced the shop with a lightweight expansion system and added over 100 new card combinations to keep gameplay fresh.

I created two humorous game NPCs. One is Horizon AI-driven and one is scripted. They guide players through the game and give silly, unsolicited feedback. I iterated on the AI description and text inputs until the personality of the AI felt right, and until the bots became helpful without giving incorrect information about the rules of the game.

Using Horizon’s Camera API, I built interactive surveillance stations where players can monitor others and influence the world real-time. I storyboarded a variety of cutscenes and concepts, and used custom voice acting, pixel art, camera logic, and audio to build them out. I also used the Horizon AI generation for some of the simpler structural objects in the Joy Control area.

I tested the world with players and adjusted logic, visuals, and performance to keep the experience polished across mobile and multiplayer.

Challenges we ran into

The biggest challenge was updating a multiplayer game that controls individual cameras and animations for each player. Designing for solo players, while keeping multiplayer chaos intact required rethinking how and when the world gives feedback or directs your attention on mobile.

Using the new animation system came with some hurdles, taking time to figure out how to load and play custom animations for avatars to use.

Accomplishments that we're proud of

I’ve received a lot of positive feedback about the changes to the game. I think that the simplicity of gameplay and silliness of the bots will make it more accessible and fun, making it more likely for solo visitors to learn how it works and want to share it with their friends.

Friends and family have found the game hilarious, finding surprise and humor in all of the little moments. I love the personalities of the game bots, and find myself laughing at them myself.

I'm especially proud of the creative use of Horizon’s Camera API, not just for world interaction, but as a storytelling device that controls tone, focus, and punchlines. It’s both a mechanic and a cinematic tool.

What we learned

This update taught me the value of simplifying systems to keep players engaged. I also learned how to balance structured gameplay with environmental humor and how to use the Camera API to power real-time player interactions and storytelling. I saw how initial onboarding can become entertainment when characters, voice, and camera work together.

What's next for RULE BREAKERS MUST DANCE

I plan to create short-form mobile content to promote the world on social media and draw new players. I'll also host game nights to gather more live feedback.

Long-term, I’d like to expand progression with unlockable cosmetics, powers, or VFX, things that reward player creativity and add even more joyful chaos to the world.
