There is a bug where one flipper gets stuck.
Another one, not sure if it's a bug: sometimes although my flippers touched the opponent ball, it did not change color and neither did it add the score to my side.
Love ❤️ the game!

Thank you very much! I'll investigate the flipper bug.
Also on mobile I wanted to force landscape and fullscreen when Wave1 starts; if it didn't, well, that's another mobile bug to look into. But game looks good portrait, so I might just give you the option to play it however you want it.
About the color change, that's intentional. You have to hit the ball with a bit of force to own it. If you just touch it or stop it, it won't become yours.
