Thanks for playing and for your suggestions!! I really appreciate it. I did notice the cursor problem but I didn’t know how to fix it. Now I add that code and the cursor works perfectly.
By the way, I noticed in the screenshot you had dug a lot of places to find the fragment. Actually, the closer you are to the fragment, the louder and higher-pitched the beeping sound from the detector becomes. So listening to the beeping sound should lead you to the fragment location. Maybe I should make this more clear in the description.
