Android Mobile Game Development

I’m ready to turn my concept for a mobile game into a fully functioning Android title. The project is strictly an Android build (no iOS work for now), so everything—from design decisions to final APK delivery—should be optimised for the Android ecosystem.

Here’s what I have and what I need from you:
• A game idea, basic mechanics sketched out in a short brief, and a few reference titles.
• Your expertise in choosing the right engine (Unity, Godot, or another Android-friendly tool you’re comfortable with) and then implementing gameplay, UI, art integration, audio, and Google Play–ready builds.
• Clean, well-commented source code handed over at the end, plus a signed APK or AAB suitable for submission to Google Play.

Acceptance criteria
• Smooth installation on current Android versions (API 24+).
• Stable 60 fps performance on mid-range devices (I’ll test on a Samsung A53).
• No crashes during a 30-minute continuous play test.
• All core gameplay loops working as described in my brief.

If you can guide me on best practices for analytics, ads, or in-app purchases, that’s a bonus. Let me know the engine you prefer, a rough timeline, and any portfolio pieces that show similar work.
