A few months back I ended up building a RDC Server in Golang (i.e. no Windows required!) entirely with Claude, which was a fun experiment.

I ended up fronting that with GitHub Auth (purely for rate limiting purposes, since it's bandwidth intensive), but I've built it in such a way that it surfaces/renders any arbitrary binary on the RDC side. In my case, I ended up just fronting it with a Snake binary, but it's been fun to experiment and push the bounds somewhat.

I should really think about open sourcing it - in my case it was an experiment to see how far I could push Claude that turned out pretty great tbh

Yeah there is, got a little lost in the formatting, but you can try the game out here: https://arena.ibuildstuff.eu

> How much of the code did you write vs. Claude?

Claude Code wrote all of it, I haven't written a single line of code here, only prompted/driven Claude (and configured deployment/a GitHub app/DNS etc). There's a breakdown of tasks at the bottom of the page ("how it was built")

> What was the hardest part to get Claude to help with? (I imagine real-time networking/WebSockets was tricky)

Definitely WebSockets - mostly in terms of debugging issues when a client disconnected and the instance was running for an extended period. After a couple of minor bug fixes I explicitly asked Claude "Please review the WebSockets code for any issues and fix those" which fixed a couple of issues

> - Any major bugs or issues that Claude couldn't solve?

Primarily around map generation, it needed a bunch of help there - it tends to spawn the turrets inside of walls, didn't take vertical elevation into account (so you could pass through a wall/under a block) - and when I asked it to generate a non-polygon level (which I've not yet pushed support for) it created a star-shape, with the bases outside of it.

Also I intentionally opted to avoid getting Claude to write tests for this, I've not looked into it, since I suspect writing a test suite for WebGL & WebSockets is _probably_ a lot more effort - and doing this by hand has allowed me to play-test this whilst Claude focused on implementing it

It's been a fun experience though!

I’ve shown this to a few people and thought folks here may be interested too.

I’ve been using Claude for a while now, and wanted to see how far I could really push it without writing a single line of code.

I ended up building a 3D web-based multiplayer game, inspired by FutureCop: LAPD (on the PS1, specifically the Precinct Assault multiplayer mode - https://www.youtube.com/watch?v=qDEXfN2ifXY), which Claude suggested would take 2-3 weeks to build (by hand).

Fast forward ~1.5 hours of prompting and I had a fun MVP - and within ~6h I was sharing it with friends. ~12 hours of prompting later - without writing a single line of code - I’m blown away at the result.

There's now multiple levels, multiple units, sounds, a leaderboard and you can use your BlueSky/GitHub username - all in 3D, all in a browser.

I’d love to hear what you think :)
