Let’s all come together and save the Config City! @Shreya Shah and I built Config City, which is a mission-based game with AR integration where players become Figma Rangers, complete quick challenges, and unlock custom cubes that help save the config city that's in danger. There’s also a creative side to it — players can paint and customize their cubes either in the editor or directly in AR, using stickers, materials, shaders, colors, and other visual details. They can bring the cube and add it to the map and if you’re in San Francisco, you can actually discover some of these cubes on the streets. So don't forget to check those out.

We built this using Figma Design, FigJam, Figma Make, Figma Weave, Figma MCP, Claude Code, and Google's MediaPipe Library for AR. Tiny missions, collectible cubes, AR surprises, and one city to save.

Breathverse: Aqua Ring

A childhood toy, rebuilt at planetary scale.

Breathverse reimagines the nostalgic handheld water ring-toss game as a cosmic, microphone-controlled experience. Players select a left or right air jet, then exhale into their microphone to propel floating rings toward celestial targets. Each captured ring transforms into a glowing planetary orbit, gradually building a small solar system through breath.

The hidden objective was to make controlled breathing feel playful rather than instructional. Instead of presenting another meditation timer or wellness dashboard, Breathverse disguises a breath-led pause inside a familiar childhood interaction. Try it OUT: https://insert-name-29709768.figma.site

I used Figma Agent to translate visual references into the interface and establish the archival, sepia-toned cosmic world. I then used Figma Make to build the microphone detection, directional air jets, floating-ring physics, target capture, scoring, and responsive gameplay.

How it works

Allow microphone access.

Select the left or right air jet.

Exhale gently to propel the rings.

Switch sides to correct their trajectory.

Capture rings around celestial targets to form orbits.

Breathverse transforms a physical toy mechanic into an embodied digital experience, using breath not as a button, but as the actual force that brings the world to life. Figma Community: https://www.figma.com/community/file/1649689014975371579/breathverse

Bubble war is an online multiplayer typing game.

You fight your opponents by typing the words on top of them.

You collect perks the same way as well. You can activate perks using "/perk-name".

Don't rush, check the perk list because it may cause damage as well.

spend 4k of credits on failed ideas.

The tank war was great but the art was not good. I bought a subscription in third party products to handle the art for me and brought them to figma make through custom mcp (connectors) but they didn't work. The art is not good at all.

Disappointed on myself and on those products. I simplified the idea to bubbles.

Spent so much time preparing the master prompt and the assets in figma and planning through figma jam.

At the moment of truth I did another big mistake. I used Claude sonnet 4.6 and not Opus . I saw in a doc of figma make a tip to use the strongest model for the bootstrap prompt. But I didn't pay attention.

I hit a nother blocker after I found out that both Supabase, instantdb presence can't handle less then 100 ms of latency and refresh rate.

To be honest, I could've stopped here and submitted my entry. But I felt it will reduce the value of the game by half. Even though the challenge is aiming for working prototypes. But Nah! I wanted to go an extra mile.

I hooked the project to claude code through figma mcp and asked for a solution. It suggested some Saas services or a custom Phoenix server.

I am a developer myself, so I went with the server and boy it was hard. My heart popped up. By the end, it almost burst.

I can't believe I am submitting this for you to try.

Please don't break it. I can't afford to spend more 😂

Leave a feedback in the game so I can make it better. But for now, let's wait for the hackathon to wrap up then I will see how to update it. I am not touching it until the results of the hachathon come out.
