A Product Engineer Built a Platformer in Otherside With an AI Coding Tool –  That’s Basically the Whole Point

• Community member builds a working platformer in Otherside using AI tools
• No official dev team needed, proving accessibility of creator tools
• Signals a shift toward user-generated content inside metaverse ecosystems

A product engineer just built a playable platformer inside Otherside using AI tools, and honestly, the game itself isn’t even the main story here. What matters is that it exists at all.

No studio, no official dev support, just one person using MML and an AI coding assistant to create something functional inside a live virtual world. That’s… kind of the whole thesis in action.

The Point Was Never Just the Game

Crock, who’s been around the Otherside ecosystem since early on, didn’t set out to build the next major metaverse hit. The idea was simpler, if the tools are there and accessible, people will build.

So he tested it himself. A basic platformer, with leaderboards and challenges, something that actually gives players a reason to stay in the environment longer than they planned.

AI Tools Lower the Barrier

The process itself is what stands out. Using MML for structure, assets from online marketplaces, and AI coding tools to handle logic, the entire experience came together without deep prior experience in game development.

That’s a big shift. It means building inside these worlds is moving closer to something like web creation, where the barrier isn’t expertise, it’s just willingness to try.

What MML Is Trying to Do

MML, or Metaverse Markup Language, is designed to function a bit like HTML for virtual worlds, defining how objects behave and interact across different environments.

If that vision holds, it could turn metaverse creation into something far more open, where users don’t just consume experiences, they actively shape them.

The Friction Is Still Real

It’s not perfect yet, though. Crock ran into issues with mechanics like moving platforms, and iteration still feels slow, requiring repeated publish-and-test cycles just to fine-tune positioning.

Those aren’t small problems, but they’re the kind you expect in early-stage systems, not dealbreakers, just things that need refinement.

What Comes Next Looks Bigger

The next idea is more ambitious, random portals appearing across different parts of Otherside, leading to hidden experiences or rewards. It’s less about a contained game and more about creating dynamic interactions across the world itself.

And importantly, he’s looking for collaborators, which says a lot about where this is heading, from solo experiments to shared building.

A Glimpse of What the Metaverse Could Be

This isn’t about one platformer. It’s about proving that the tools work well enough for real people to start building without permission.

If that continues, the metaverse shifts from something a company creates to something a community grows, slowly, imperfectly, but organically. And that’s probably the more interesting outcome anyway.
