1. Develop core gameplay systems for an arcade-style 3D mobile game in Unity, including player movement, camera setup, obstacle mechanics, collectables, scoring, collisions, level flow and game-over/restart logic. 2. Create clean Unity scenes, prefabs, reusable C# scripts, UI screens, gameplay loops and organised project folders while maintaining regular project updates and version-control discipline. 3. Test gameplay builds, fix bugs, improve controls and performance, document the setup clearly, and support the game’s development from early playable builds toward a complete game structure.
