Some people have been having issues with the game. I figured out that the problem was the character models and their textures. It should reduce the lag but just in case I have also added a load scene button. This will lead you to a screen where you can just pick a level and skip any of the laggy sections. Anytime you want to exit a level that doesn't have text just press escape and you'll go to the main menu. That is all I can do for now. For those who don't know Personal Trainer is just a small series that I do so that I can learn and improve. I create one every one or two months, but I have a main game that I focus on.  So starting December 1st I will have to focus on the next Personal Trainer and my main game Patricide. I'm hoping this fix will make the game more enjoyable and hopefully, I can figure out a better solution for future games. Thank you to everyone who told me about the issue and to Sora Album who made figuring out the issue a lot easier.
