I think all have or should have indicators. If you run out of time the crank it up hole lights up - go for that to change song and get another 30 seconds. You can adjust the time of play of each song in the adjustments menu.
I have had 2 problems so far The highest score registers "wwwwwwww" no matter what you type in and my "s" target
Sticker has exited. No real problems. My GB has been absolutely trouble free. AS will definitely make you a better player.
Really good game.
It SEEMS you can do much better going to 4 ball multiball over 3 ball then filling the crank it up hole as often as you can. This is how I've gotten my highest scores.
The sound is good out of the box but I'll be adding a powered sub but I'm kind of a music nut.
The GB dot matrix looks a bit dated compared to the AS screen. Animations are really good with AS.
This is about all after 5 days of ownership
