Thanks, that is great advice. I didn't know how to make the transparent object. And I didn't know about many of thee other things you said. My plan is to maintain the game in the future and I will make the changes that are not very time consuming, now. I am very busy with other projects at this time.
Thanks for your advice it is really helpful and thanks for finding the bug.
You clearly know your stuff and I respect you for sharing your guidance.
Have a great day.
Thanks again.
