Source evidence

The open-source repo for my game just hit 200 stars on GitHub 🎉

Really appreciate everyone who checked it out, shared feedback, and supported the project.

Still building. Still shipping. Still prompting 😌

BuildInPublic #shipaton

After getting tons of feedback on the 3D chess game I vibe-coded in 2 hours, I just shipped another update:

→ 3 new battle systems
→ Two-player mode
→ Walking animations for the chess pieces
→ A complete sound system
→ Improved performance

And the crazy part is I only needed another hour of vibe coding to build all of this.

You can officially replace the default chess game on your MacBook now lol. 😆
