EXTEND 1: Let's experiment with making small changes to the game!
- Find and change the number in the .set_gravity() command from 4 to any other number.
- Find stage.event_interval(interval,·2)¬. Change 2 to a greater number to drop food less frequently.
- Find your indented .move_left(20) and .move_right(20) commands. Change 20 to any other number.
You've changed how fast food drops, how often it drops, and how fast the fish swims! What else can we change?
