In a post way back it was mentioned that the "key lane" wasn't making a sound , making him think the switch wasn't working.
That is still one of my issues with this game , that some made shots do not produce a sound that lets you know you did something. Lock shot also comes to mind. I know you have announcement that lock is lit , but the actual switch event seems like it should have a distinct sound (like most pinball games do) . If the sounds are there , they are getting lost. Overall i am happy with sounds and callouts.
Hope it doesn't come through as a complaint , i am loving this game more and more and am hoping to help improve it via feedback.
