A 3D game where you walk through virtual Brno and collect coins. 800 players, 5,000+ games, and for me the best vibe coding training there was.
About the project
My own 3D game where you walk (or drive) through virtual Brno, collect coins, and compete for the high score.
I built it in 14 days in May 2025, over a hundred hours from morning to night in Windsurf and Cursor.
The point was the journey, not the destination: I wanted to get hands-on with a real game engine, and this was the best vibe coding training I've had.
That 800 people ended up playing it, played over 5,000 games, and one enthusiast played it 300 times, was a nice bonus.
What you get
- The best vibe coding training I've been through.
- The journey was the point, I got hands-on with a game engine.
- 800 players and 5,000+ games as a bonus on top.
How it works (under the hood)
- 3D Brno in Three.js, walking and driving.
- Coin collecting, audio descriptions of buildings, bonuses.
- A public high-score competition with a database (PHP/MySQL).
