Thanks for trying it out!
I tried setting a variable to "true" when the ball enters a hittable zone, then "false" when it leaves, and requiring "Input is action just pressed" plus hittable variable "true" to make the score go up, but something there didn't turn out quite right.
It would be interesting to take more time to troubleshoot it.
As for the zoom, I don't observe that on any of my browsers, but that sounds like great practice to adjust those settings, I'm going to try and remember that, thank you!
