Answer 1

line 77

Answer 2

Which credit to owner you are talking about ?
And I really don't have any clue on why would someone search this big code to find out what this program is doing and then check what you asked for

You could simply do
if lives<=3
element.style.color="red"

If that isn't working maybe you could point out what part or line in that code where you are changing Colors for the lives is mentioned so someone don't need to go through the whole code
