You are given a program where a sprite is supposed to jump when the spacebar is pressed, but nothing happens. What steps would you take to find and fix the problem?

You want to make a sprite move in a square path. Which coding concepts would you use to plan your solution?

• Change the sprite's name

• Add more buttons
