Probably a toss up between Secret Service and Circus. I think Secret Service was moved on in a shorter time period. Game was okay, great sounds but the whole buying process and getting it fixed up just left the thing sitting sour with me. The PF ripoff of Flash didn't do much for the respect of the design either.
IIRC, this was the infamous game with the mains power floating around in the fusebox. That game was a deathwish.
