When I tried to use the go to mouse pointer block, it didn't work and went to a different place than the mouse pointer. I tried using the script below, but then it stopped sensing at certain areas.

change x by (-36)

change y by (-2)

Can post the project so we can take a look?

okay you can click see inside https://scratch.mit.edu/projects/459713306/

Your problem is that the costume is not centered! Look:

Move the circle to the center and then you should be able to remove the change x and y blocks

Wait I think I fixed it - I just had to adjust the place of the circle on the costume painter

This is why it doesn't work: in your costume for the cursor, the circle is slightly off-center. It is really easy to make the circle centered though. First, go to the costumes tab. Then drag the circle so that the + sign on the circle matches with the other + sign. (The other + sign kind of looks like a steering wheel)
