How it went
01 · The problem
Stonefall proved the format worked. The follow-up had to hold a player past the first run and give the subreddit a reason to keep coming back to the same post.
02 · What we built
A marble roller in React Three Fiber: neon maze levels, a live minimap, community boards, and an original score, all running inside a Reddit post on Devvit.
03 · What happened
Reddit Foundry put funding behind it, it shipped live on Reddit, and Reddit featured it.
