I have been looking into tutorials and its taken me a while but I managed to follow TechwithTim's tutorial and understand it. The code runs and I am not getting errors, I even went back and looked at his code, followed the videos to see if I had any mistakes, however everything is running but when I begin the game it looks like the game runs a hyper speed and says I lost lol. I tried to adjust some numbers but theyre identical to the tutorial so I am unsure where I am going wrong. Bare with me I am self taught and working on it, so any help is appreciated
