I think this is a really good course to start with. I think it will be a course that will leave a deep impression on my life.

This Unity game development course covers everything from the basic C# grammar used in Unity to the Unity interface, sound, data management, and distribution as an Android app. 
In addition, the course is not a follow-along course, but rather a lecture that allows you to understand the principles and create your own mobile game.
