Comment by Marco Alka on "Why event calling is increasing, each time I restart my game."

I don't know how you do event handling (maybe you could share some code), so I will assume you are using standard HTML event handling.

Getting event target: const target = document.querySelector('canvas')
Setting up event handler: const handler = function() { /* ... */ }
Adding event handler: target.addEventHandler('event-name', handler)
Removing event handler: target.removeEventHandler('event-name', handler) (docs)

You should make it a habit to clean up everything after use, the latest on shutdown of your main code, especially if you do not stop the program, as in your case.
