A car wash game for young kids, built with Kotlin Multiplatform and Compose Multiplatform.
The player picks a car, washes it step by step with tools dragged from a tray, and sends it off clean. Android is the shipping target; the game code lives in the shared module and also compiles for iOS.
This repository is a snapshot of the project at version 0.3.5. Further development continues elsewhere under a different name.
- JDK 17
- Android SDK 37

The code was written with the help of AI coding agents: Claude Code and Codex.
