C#, Winform, Solution of ordinary differential equations

It is necessary to add animation to the low-poly main character and give him the ability to hold a weapon (tool) that will aim at the cursor. The game is from a third-person perspective, with the camera behind the player and the cursor in the center of the screen. The character needs to be able to enter aim mode, the camera slightly zooms in, and the character should be able to use the tool (a laser tool for resource gathering). I have a ready animation controller from Synty - Third Person Controller. It can be used or the animation can be completely set up from scratch if that is easier. In the end, I expect a character that can select a tool (one large two-handed and two small ones), switch tools, aim, and have the head and the tool look at the point where the cursor is pointing.

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. In your response, please indicate: examples of your work; experience working with Unity; estimated hourly rate or cost of execution.
