Mobile Game Developer for Fast-Paced FPS

I need a developer who can turn my concept for a fast-paced, first-person action game into a fully playable mobile experience. I’m targeting Android and iOS, so the build must run smoothly on current mid-range devices without sacrificing responsive controls or striking visuals.

Scope
• Core gameplay loop: shooting, melee, or other high-energy mechanics that feel tight and intuitive on touch screens.
• Level framework: one polished demo level that showcases enemy AI, basic progression, and pick-ups.
• Visual & audio style: stylized or semi-realistic assets that you can source or create; I will supply reference art and music direction.
• Optimisation: mobile-friendly shaders, efficient lighting, and asset compression to maintain 60 fps on typical devices.
• Tech stack: Unity or Unreal Engine (your choice, as long as you justify it and set up a clean, well-documented project hierarchy).
• Deliverables: APK/IPA test builds, complete source project, and brief setup notes so I can iterate on my side.

Nice-to-have additions (optional but welcome)
• Simple menu/UI, including basic settings.
• In-app analytics hooks to track session length and key events.
• Multiplayer groundwork or a leaderboard stub if feasible.

I value clear, proactive communication, short milestone sprints, and code I can read and extend. If you’ve shipped any first-person mobile titles before, share links or builds—seeing your past optimisation work will be a big plus.
