Answer 1

The error is in:
function endOverlay()
You add an event listener to the overlay everytime the game ends, this event listener calls start, after a couple deaths you have several event listeners each calling start() on click, causing the game to update multiple times faster than it should.
solution add a check so that event listener is only added to the overlay once

I'm still not good enough to help you, I hope you find an answer, if no one helps here consider asking in other places too, the game seems pretty cool tho, I hope by the end of this year I be able to make similar games too.

Answer 3

If consistent,i guess you can make such after a month or two. Goodluck!
