Imoto caught a part of my first try of Munsters Premium at Texas Pinball Festival. Yes, I have my Koopa Shell on.
I did start Munster Madness near the end of this game where both the main and mini playfields are active simultaneously.
At first, I tried to operate all four flippers independently. However, that quickly devolved into me just paying attention to the main playfield while using both flipper buttons on the side I wanted to flip at the time.
Fun With Bonus is the home of the semi-coherent, misguided ramblings of professional and amateur pinball players.
