I haven't got the double tap to work/also haven't noticed the phone say/display that before multi ball starts but I like that idea. I always liked how in Goldeneye you could hold down the trigger on the gun launcher (could be both flippers at the same time for DI) to cancel one multi ball in favor of risking it for another. Aerosmith gives you a display screen and a countdown I think, I like it being more on the go and harder to pull off. Only having the ability to use that feature once per game would make it valuable, even more so if the value of the multi ball jackpot goes up every time you play it.

Same for me with shooting the phone not slowing charging. I did hit something earlier that charged the phone very little (1%) and I think it was the sim card scoop or the big bang shot, but not totally sure. Hopefully getting some more games in tomorrow and will pay closer attention to this, I didn't read the rules posted here until now. Thanks for the work thus far.
