Android Coin-Based Game Development

I have an idea for a casual, coin-based mobile game and I want to see it come alive on Android phones and tablets. The core loop is simple: players tap, swipe, or tilt to collect or earn coins, then spend them on in-game upgrades, cosmetic items, or power-ups that keep the session short, fun, and addictive. Here is what I need from you: • A complete Android Studio project (Java or Kotlin) that builds without errors, including all game logic, UI screens, and assets. • An installable APK so I can playtest on physical devices running Android 8.0 and up. • Basic user-progress saving (local or with Google Play Games Services, whichever is faster for you to implement). • Simple sound effects and background music—royalty-free is fine. • Clear instructions on how to open, build, and modify the project if I decide to add new levels or coin types later. For first acceptance I’ll test the APK to confirm: 1. The coin mechanic works end-to-end (collect, tally, spend). 2. No crashes during a 10-minute continuous play session. 3. Assets load correctly on screens from 5" phones to 10" tablets. Once those points pass, we can move to polishing touches like animations, leaderboards, and ad or in-app purchase hooks if time allows. Let me know how you plan to structure the code, which frameworks or libraries you prefer (LibGDX, Unity with Android export, plain Canvas, etc.), and the estimated timeframe for a playable MVP. Budget: INR 75000–150000
