Wow, I don't think I've ever seen a game like this on Itch! Really well done! It was fun to play and you captured the essence of ping pong with the way you can swipe at the ball for different effects. The depth of the ball works well, the CPU responds well, and difficulty of getting the ball past the CPU is well balanced. The only problem I had was that when the game ended, I couldn't figure out how to start a new game without exiting the entire page and coming back in (even after translating the Japanese instructions). Great work on this!
