Unity Developer Needed for a 3D Physics-Based Rocket Game

We are looking for a Unity developer to build a small 3D physics-based game featuring rocket movement, object transportation, obstacles, power management, and scoring. The game will use a 2D-style movement system within a 3D environment. The player will control a rocket using directional thrust, collect boulders through a physics-based tether system, and transport them to a designated delivery zone while avoiding moving obstacles. The project should include: Rigidbody-based rocket movement using directional forces Reduced gravity for slower, space-like movement A physics-based tether using joints Three boulders with different sizes and masses Automatic boulder pickup and release A delivery zone with scoring Power consumption while using the rocket thrusters Different power costs depending on the carried boulder Rotating and vertically moving obstacles Power reduction after obstacle collisions On-screen power and delivery counters Win condition after all boulders are delivered Automatic game reset when power reaches zero A fixed camera and clear game boundaries Clean, organised, and understandable C# scripts The finished project should be stable, easy to run, and delivered as a complete Unity project folder. Basic documentation explaining the project structure, controls, and setup process should also be included. Required Skills Unity 3D C# programming Rigidbody physics Unity joints and collision systems UI implementation using TextMeshPro Gameplay and level-system development Deliverables Complete Unity project All scripts and project assets Three functional gameplay scenes or demonstrations Setup and run instructions Project documentation Tested and working game mechanics Please include examples of previous Unity or physics-based game projects when applying.
