This course/tool/game is really, really good. I would say that the material is so good that it's worth anyone getting into programming giving this a go. Yes, it will teach you Godot script, but the underlying rules will apply to all programming languages.
Great explanations of topics, mini tests and questions as you progress, and the coding tool is really nice.
My only (very minor) gripe would be having some of the syntax of things available in the coding tool. For example, I knew that I needed to write a for loop in one of the tasks, but I needed to go back and look up the syntax before I could write it. Then again, maybe that's done intentionally. I did, after all, learn the syntax :)
