First-Person Mobile Adventure Game

I’m planning a story-driven, first-person adventure designed from the ground up for phones and tablets, and I need a developer who can take it from concept to App Store and Google Play release. The game will ship simultaneously on iOS and Android, so a cross-platform engine such as Unity or Unreal Engine makes the most sense, but I’m open to alternatives if you can justify them.

Core idea
Players explore a rich 3-D environment, uncover narrative clues, solve environmental puzzles, and progress through a branching storyline. Smooth touchscreen controls, device-friendly performance, and an immersive audio mix are essential; I want the player to feel as though the phone is a window into the game world.

Art & assets
Low-poly stylised visuals are preferred to keep builds lightweight, though I’m flexible if you can demonstrate another approach that still maintains a high, consistent frame rate on mid-range devices.

Monetisation & backend
The initial release will be premium (no ads), with the option of in-app DLC episodes later. Cloud save and basic analytics should be hooked into Apple/Google services so I can track retention without compromising privacy.

Deliverables (acceptance criteria)
• Playable prototype featuring first-person movement, touch controls, and one puzzle
• Fully commented project source, ready to compile for both iOS and Android
• Two test builds (TestFlight + APK) and a final release-candidate build
• Brief setup/documentation so another developer can open, build, and submit updates

Timing
Ideally the prototype arrives within four weeks, with the full vertical slice following after feedback.

If you’ve shipped at least one mobile title and are comfortable optimising for both iOS and Android, I’d love to see your reel and hear how you’d tackle this adventure.
