Yeah, I missed a lot of things I should have used a panel instead of placing the bg image on the form. That's what causes the bugs mostly and the reason for fps drops. When I realized that I had no time left almost and could not really do anything. It runs because it hides the original form in the background for music, but I know that this game is not good at all, especially against its competitors.
Thank you for your reply if I can I will fix those.
