For the user to be able to find the treasure within the 5 pixel range may take quite a number of attempts/inputs.

In order to give the user a hint as to how close the user is to finding the treasure, I tried to use the mathematical formula which would give the user a feedback as to how close they are to the treasure. Below is the formula thatt I used.

# Give the user feedback on how close they are to the treasure here:
  diff_x = user_x - treasure_x
  diff_y = user_y - treasure_y
  diff = pow((pow(diff_x,2) + pow(diff_y,2)),0.5)
