Project description:
"I’ve finished the core gameplay and have the APK ready, but right now the project earns nothing. My goal is to turn this into a real revenue stream by adding in-app purchases only—no ads, no subscriptions. Players will be able to buy virtual goods such as coins and equipment, so the flow must feel seamless, secure, and familiar to mobile gamers.

Here’s what I need from you:

• Design and set up the in-app purchase catalogue (coins, gear, and any future items) with clear price tiers and SKU management.
• Integrate the billing library for both Google Play (and iOS later if feasible) and handle receipt validation to prevent fraud.
• Wire the purchase confirmation back into the game logic so items are instantly credited to the player’s account.
• Provide a simple analytics hook so I can track conversion rates and revenue per item.
• Supply concise documentation and a short walk-through video so I can update prices or add new items on my own.

Acceptance criteria
1. A test build shows the purchase dialog, completes a sandbox transaction, and automatically delivers the chosen virtual item.
2. Failed or cancelled purchases leave the player’s inventory unchanged.
3. All SKUs and price tiers are editable through the store dashboards without touching code.
4. Clear notes on store submission requirements (screenshots, text, and any compliance steps) are delivered.

If you have solid experience with Google Play Billing, in-app purchase security, and virtual economy balancing, I’m ready to get started right away." (client-provided description)
