Ask HN: What are you working on? (September 2026)
It's an early version so many (if not most) things that would be in a game are still missing at the moment (though planned on paper).
One interesting thing is that because the Voronoi voxels are so malleable, things like round or hollow worlds are a pretty natural outcome.
In parallel to working on it, I've been mostly using it to build and improve my own voxel castle with a pointy roof, slanted walls, custom built stairs, tables, chairs and all those nice things.
In the last update I added a CRT filter and some pixelation options as I find that appealing. As for the future (maybe as the next thing?), I guess I'd probably like to add the ability to build less blocky things like round towers (or flower vases!), but that is still very much a work in progress.
The Web version (WebGL) is completely free (and will stay that way):
I started it because I wanted simple brain-training exercises that didn’t require an account, app install, or subscription.
It’s also open source: https://github.com/loethen/freefocusgames
I wonder if Claude Code could do this. That's a useful metric for the future - if a coding agent can't handle the breaking changes in a package upgrade, it's the package's fault. The day may come when that's something Github Actions checks for pull requests.
Would be good to keep track of how long it takes you to complete, so you can compare it with how long it takes Opus and then Fable to accomplish the same thing.
I should have. All I have right now is a free Cursor account and Github Copilot. I've got to start spending money on tokens and get up to date. That article today by Carmack chewing out game devs for hand coding was striking, considering who he is and how much low level stuff he has done.
I'm doing 3D rendering in Rust. (Think three.js, but in Rust.) This is well outside the mainstream, so there's not much on the web to populate training sets. A year ago, AI coding tools could not cope with this area at all. Today, maybe.
I have no idea how good Claude is at understanding breaking changes to an API. I expect it would get simple changes, such as structure field renamings, without any trouble. But the gyrations required to handle write only access to GPU memory in Rust might not appear in the training data.
I remember someone saying that when you build a game, you end up building tools to help you build the game. I never really got that, but now I do. I've spent quite a bit of time working on tools to help me balance the various game mechanics.
One weird learning, it was much easier to get it on the iOS app store, than the Google Play store. Google wants you to have a closed playtest with at least 12 players, for 14 days. I did that and they said the testers weren't engaged enough.
If you want to check it out on iOS https://apps.apple.com/us/app/fairway-rogue/id6783598189, I'm still trying to get it on Android
It has the ability to generate a small notebook from a problem description using AI (still has a lot of room to improve), but the calculation uses a deterministic engine.
Right now I'm working on collaboration.
