Adventure Mobile Game App Development

I’m ready to bring an original adventure game to life and need a developer who can deliver polished, dual-platform builds for both iOS and Android. The core idea revolves around a compelling narrative that keeps players engaged while giving them clear opportunities to make in-app purchases—think cosmetics, power-ups, or bonus chapters that add real value without feeling pay-to-win.

Here’s what I have in mind:

• Cross-platform Unity or Unreal implementation so we can maintain a single codebase yet achieve native-feeling performance on each store.
• A seamless in-app purchase flow fully integrated with Apple and Google billing, including receipt validation and sandbox testing.
• A simple but expandable adventure framework featuring a hub area, multiple quest lines, and save/load functionality.
• Clean, modular code and well-commented scripts so future updates and DLC drops are straightforward.
• Store-ready assets: signed builds, properly sized icons, screenshots, and a short gameplay trailer clip that showcases the purchase system in action.

Acceptance Criteria
• iOS TestFlight and Android beta links demonstrating stable gameplay on mid-tier devices (iOS 13+, Android 8+).
• At least one purchasable item connected to live sandbox environments, with successful transaction logging.
• Source code repository delivered via Git, including commit history and build instructions.

If you have an existing toolkit for adventure mechanics or prior experience releasing cross-platform titles with in-app purchases, let’s talk timing and milestones so we can get this into players’ hands quickly.
