I want to turn an original story-driven adventure concept into a fully playable game for phones and tablets. Exploration, puzzle-solving, and real-time cooperation sit at the heart of the design, so reliable online multiplayer is essential from day one. Here’s what I’m aiming for: • A complete mobile build (Android APK and iOS TestFlight package) plus the full project source. • Touch-friendly controls that work in portrait and landscape. • Smooth networking for up to four players in the same session, with lobby creation, join/leave, and basic chat. • A first playable level that showcases exploration, an inventory puzzle, and a short boss set-piece. • Clear, well-commented code and tidy asset folders so I can keep expanding the project on my own. Acceptance criteria: • Players can host or join a session, move together through the demo level, and stay in sync without obvious lag or rubber-banding. • The game holds 55-60 fps on mid-range devices from the past three years. • All scenes, prefabs, and scripts compile out of the box on a clean machine. If you already shipped an adventure title on mobile—especially one using Photon, Mirror, or a similar framework—link me to a short video or live build when you bid and let me know which networking tech you’d lean on here. I’ll be on hand to provide art, narrative beats, and prompt feedback throughout development.
