If you don't want them to edit your files, ok you're in your right but don't do it botchery or fuc -ked screw up to leave a fuc -king watermark permanent on the game screen.
I don't understand why you want to share a project if you then impose this kind of limits and obstacles. If it were to protect the autor rights you could have done clearly without hindering the game screen. In this way is impossible to enjoy this interface.
