Unity Tutorials are a great tool to learn. I am currently learning with a tutorial on Udemy.
There is a lot in it on how to use C#, but also obviously how to publich a game using webGL
The tutorial is highly recommended for anybody who wants to try that as well.

Here are my results.
This is the first tutorial I followed. It is a number guessing game to get the basics. Was a lot of fun to do and is quite short.
And another one. This is an anagram guessing game. It even has a hidden bonus level. Can you find the ultimate reward?
I have a tutorial about a "choose your own adventure game" next on my learning list. And the setting will be to escape from ikea.
