Game ended after two events happened simultaneously ...
UPDATE: I just started up the game, again, after closing it last time. Unexpectedly, I got the "Load autosaved game?" prompt. I selected "Yes" to load the saved game. I see my greater than ten million score from when the game previously closed ($10,152,910). But, this is where it got really weird ... the game started with no ball in the launching plunger
! This was repeatable, until I chose not to load the old game.
