Please make a complete game tutorial in youtube
Different games have different strategies, objectives, and ways of working (example, using lives or not? can you jump or not? is it keyboard-based or mouse based?)
Therefore, you cannot possibly expect to find a comprehensive game tutorial for Wick on youtube.
However, you can look at other people’s codes for functions you want, and ask the forums for help.
That is a very vague request :D! what kind of game are you talking about? Is it a platformer, an arcade shooter, a point and click game, or maybe something silly?
I can recommend learning Javascript or “reading the learning section of the website (link)”, since programming is the thing that makes something a functional game, no matter how simple.
