Answer 1

1. Move the onclick to the body tag, not the html tag.
2. Wrap your initializing code in a;
document.onload = ()=> { ... code here ...}
So that the DOM is built when the objects are created.

Answer 2

Without posting the code, it's not possible to provide a solution.

Answer 3

Try to attach a link to your code, maybe it can describe the issue better. I find your Description to be rather vague and unclear contextually

"when you play the game"
What game?

"and click on it"
Click on what;

"the function jump isn't working"
What function? there is no code to view.

Maybe it's time for practicing mind reading for me.
