Function of placing overleys on video in the player, C#

We are looking for an experienced Unity developer to help complete the game development. About the game: Genre: farm simulator. The game is already being developed in Unity. Initially, it was created for mobile devices, but later it was decided to release it for Steam (PC). What needs to be done: Finish the game according to the completed technical specification. Adapt the existing functionality for PC and Steam. Implement the already planned mechanics and interface. What we provide: Detailed technical specification. All necessary materials (models, graphics, objects, etc.). Photos, videos, screenshots, and recordings of the original game. A ready implementation plan. We are recreating a game that successfully operated over 10 years ago, so there is no need to invent or design from scratch. All mechanics, interface, and logic are already defined — they need to be implemented in Unity with quality. For project familiarization, we provide a link to one of the game video reviews: Insert link here. Requirements: Experience working with Unity. Experience in developing or adapting games for PC/Steam will be an advantage. Ability to work according to the provided technical specification.
