I need help with two things....

1. I would like to lower the speed of the snake.
2. I want to make the screen, snake, and food bigger.

I really need to change the speed. The 2nd thing is just something extra.
But, I've tried a bunch of little things for both, but nothing seems to work.

Here's my code so far... any suggestions would help!
