I’m ready to bring a first-person adventure to phones and tablets and need full development support, from concept to store-ready build. The goal is a story-driven experience with simple, intuitive touch controls, atmospheric 3D environments, and light puzzle elements that keep players engaged during short sessions yet invite them back for longer playthroughs. My ideal stack is Unity or Unreal Engine because of their proven mobile pipelines, but I’m open to other engines as long as performance on both iOS and Android remains solid. I already have a loose narrative outline; everything else—from level design and character art to UI, sound, and basic analytics—will start with you. Deliverables I’ll review at each milestone: • Playable prototype demonstrating core movement and interaction • Vertical slice showcasing one complete level with art placeholders • Polished beta build ready for TestFlight / closed Android testing • Final store-ready binaries plus full, clean project source and asset files Acceptance criteria include stable 60 fps on mid-range devices, intuitive single-hand control, no critical crashes, and clear documentation so the project can be updated after launch. If you love crafting immersive mobile adventures, I’d be happy to share the narrative draft and discuss timelines right away.
