If you don't know how to play ping pong, I do not want to know you. 2021 May 24: Bug fix: letting CPU have more smooth movement, CPU is now slightly stronger. Due to this, the challenges' top scores have been reset. 2021 May 25: Further bug fix, allowing CPU to have a better chance with more balls, and be significantly better with 1 ball. Once again, the challenges' top scores have been reset. This update also fixes the bug locking the ball in a wall, and causes slightly slower gameplay. 2021 May 27: Changed the condition needed for an extra ball to spawn from 50 points on each side to 100 total points. 2021 May 28: CPU buffed to be able to pretty much block every ball when there are very few balls. Again, the top scores are reset.
Challenges: 1 is you have to score as many points as possible without giving CPU a single point. 2 is you have to let CPU score as many points as possible without you getting any point.
