Yeah, smoothness and minimalism were the two main things I wanted to focus on, so I am so happy that you think I got that.
The ball and the AI get better with time, so when playing against the AI, it is best to see more of how long you can last, rather than the score, I might replace the score with a timer later on.
If there are any bugs you can find or any other powerups you think would be good in the game please let me know! Thanks for the review.
