Based on Pong, the objective is simple, use the paddle to prevent the ball from falling into the spikes and score as high as you can. To start, press either 1 for normal difficulty or 2 for hard. Use your mouse to guide the paddle. If you lose, just hit 1 or 2 to play again.
This is my very first completed project in Scratch, so it's nothing spectacular. Just built it to learn the basics and for fun.
