Built a 2D version of “Steal a Brainrot” with my son
He loved the original — so we rebuilt the core loop as a small Vibe Coding project.
Play here for free forever: https://brainrot-factory.fony.de/
What you do:
  • buy brainrots from a conveyor
  • fusion brainrots for gold/diamond/rainbow trait
  • earn passive income
  • unlock more slots to scale
Extras:
  • items to boost spawn rate
  • random global events (every 30 min)
  • in-game chat
The fun part: Admin Chaos Mode. 💥
My son had ONE requirement: “I want to be able to troll everyone like in the original game.”
So we built a full admin panel:
  • trigger global events
  • boost spawn luck for all players
  • spawn specific brainrots server-wide
👉 Watch the Video attached to see them in action
We also created our own brainrots — partly hand-drawn, then refined with AI.
This project was mainly built back in july 2025 with Firebase Studio.
Would love to hear some honest feedback 🤩
