By watching your new video showing how physics are compare to the real thing ( btw is freakin amazing! ), iv notice something that could see an improvement, an addition maybe?
Flippers sound. This high snapping flipper sound from the button hard press from a pinball machine is not there, and even others pinball games didnt recreated that sound. Dont know possible that would be to re-created this sound effects.
Little suggestion to make it feel even more real!
