I am trying to make a Turtle Eater Game and I'm running into a minor bug(kind of)

Question

The objective of this project is to make a game in which the turtle eats all of the dots. I thought that this code would be an intuitive way of going about the problem as opposed to manually checking each dot. However, this code only works for the first dot and none of the rest. I think it's because I'm using a while loop so the variable will always stay at 0 but I'm not too sure how to fix this error and keep the code simple without making it too long. If anyone can help me find a way to fix this, it would be extremely helpful.
