Started this just after Addams Family, and I think it's pretty good!
Took me a while to work out how to change weapons because I don't have the manual (duck and press jump if you were wondering), but once I'd worked that out I was off.
I still haven't managed to finish this without continuing, I've been really close though, made it to the boss of the 5th level and died about 2 shots off of killing him, the 6th (last) level is easy too :(. If you continue your score is reset so it's pointless using them for this contest :).
I think this contest is gonna be won or lost on the flying sections, the more points you can rack up there the better, but they're tough! You can't see your score in the flying sections until you finish them either so there'll be no midway pause screen scores :).
Anyway, I'll open with a score of 120,707, I took a photo just in case I can't do any better but I'm gonna keep on trying for a while.
EDIT: Managed to get through it without losing a life! TBH I'd probably have scored higher if I'd used my lifes to kill a few more enemies, but I'm happy with my score: 190,146
