Why we're using Input Manager (Old):
While Unity recommends using the new Input System, this project uses Input Manager (Old) for the following reasons:

Simpler and more stable integration for small to mid-sized projects.
No need for additional setup or reliance on Unity’s event-based input handling.
You can switch to the new system if needed, but doing so would require refactoring input handling throughout the project.
