01 Case study

What I built

Clean Up 3D is a grow-and-clear idle cleaner. You vacuum small junk, spend coins on battery, speed, and size, and watch the same street become a different game as the nozzle gets greedy. The comedy is in the scale: coins, cars, then the whole block.

I built it in Unity for Kwalee and shipped it on iOS and Android. The App Store listing still holds a 4.6 from tens of thousands of ratings. Around eight million lifetime downloads.
