SnakeGame Help

Question

I have to do a school project, and i really need your help. I'm working on a snake game, and currently having difficulties for some stuff. For example, food is sometimes spawning on the snake, i need to implement high score system, and also, i have to add pictures to snake and food.  I linked my project via google drive, so, if you have free time, could you help me with this, please. I wouldn't have asked, but it's really urgent.
