SpeedRun Kit: Modular Obby Framework

Inspiration

I wanted to create something that is instantly familiar to players but powerful for remixers. Obby/speedrun games are one of the most popular and universal formats across platforms. They’re simple to play, yet infinitely remixable. My inspiration was to lower the barrier for creators: a no-code kit where anyone can remix and extend without worrying about scripting.

What it does

SpeedRun Kit: Modular Obby Framework is a remixable system for building speedrun/obby games in Horizon Worlds.

41+ assets with 3 style/color variants each
12+ prefabs pre-coded with movers, traps, buttons, and more
Built-in checkpoint and respawn system
Modular plug-and-play segments for easy remixing
A 5-level demo obby tower that shows how everything connects

It’s both a playable game and a starting point for endless new creations.

How we built it

Designed all assets in Meta Horizon Worlds Editor using modular geometry.
Scripted configurable movers and triggers (platforms, spinners, pushers).
Integrated a checkpoint/respawn system for smooth round flow.
Packaged everything as prefabs so remixers can drag and drop.
Optimized the demo for mobile performance while keeping it fun and fast-paced.

Challenges we ran into

Making the kit powerful but beginner-friendly — exposing the right amount of configuration without overwhelming remixers.
Ensuring mobile performance with many moving parts.
Managing scope under a tight deadline while still delivering over 41 assets and 12 prefabs.

Accomplishments that we're proud of

A fully functional framework that anyone can remix with zero coding required.
Delivering 41+ assets and a polished demo tower in a short timeframe.
Structuring everything to be modular and reusable, so remixers can build their own games quickly.
Packaging the kit in a way that doubles as both documentation and gameplay.

What we learned

Documentation and structure are just as important as the assets themselves.
Even small features like checkpoints and color variants make remixability much easier.
Building for open source in Horizon Worlds means thinking beyond the game itself — it’s about empowering other creators.
