Not long ago I wrote about how I built a browser-based board game called "Growing City" in three days using AI — and how the hardest part wasn't the code at all. Some time has passed, and I wanted to share what happened next.
Layout Bugs
While vibe-coding solo, I only tested on my own screen, resolution, and browser. The problem surfaced as soon as real users joined with different setups: some people saw everything misaligned, some things got clipped, some cards overlapped each other.
This is how it looked on some screens
I had to rewrite the layout to use adaptive sizing so the game looks correct regardless of screen resolution. It should work now — but if something still looks off on your end, let me know and I'll fix it.
Bots Started Talking
Another change, unrelated to bugs. The service started feeling more alive. Previously, bots just played: rolled dice, bought cards, said nothing. Now they react in the chat to what's happening in the game — if someone's building gets taken, if someone buys an expensive card or runs out of money.
It's a small thing, but the game feels noticeably more lively. An empty game with silent bots versus a session where someone's commenting on what's happening in chat — it's a meaningfully different experience, even though the game itself is the same.
Thank You to Early Players
A special thanks to everyone who tried the game after my first article.
And extra thanks to a user with the nickname SHAM, who pointed out that the game rules never said you can't buy multiple purple cards in a row — even though the game itself has that restriction. Fixed!
What's Next
The project is still going. I'm thinking about ads and other ways to bring in players. Without new users, it's hard to get feedback — and without feedback, it's hard to know what to fix or improve first.
The unit economics don't quite work out yet: paid acquisition costs more than I'm willing to invest at this stage. I'll keep figuring it out. If you have ideas on how to find players for a project like this, I'd genuinely love to hear them.
Want to Play?
The game is still live at rastushiy-gorod.ru. No registration needed.
Same as before — all feedback gets read and used. That's how the project keeps moving forward.
