Nowhere near the top, but here's my crappy attempt (with my mascot, the King).

Had to get in close, for whatever reason it kept being blurry when I was farther away, I died in world 7.

Wow, that is nucking futs.

yeah, found some good spots for scoring points, and beat the rest of the levels as quick as I could with getting every power up that I could (you get 50 points per second left, and 1k points for every power up).

would do the Mudosko method for level 1-1 (bout 444k points)
gomba tail stomp on level 1-2 (bout 170k)
three turtles after the sky level in level 1-5 (bout 80k)
all the block guys and turtle in 2-1 (bout 150k)
and would do the dry bones with tail in 2 level castle (bout 150k)

I would usually have 1.112 mil by the end of the mini castle in level 2 and were a few other areas for good point racking (like level 2-6, with the flying turtles and the one in world 4 that had two turtles by the doors to bigger/smaller enemies).

I'm glad I can now say that I beat every level in Super Mario 3 without dying

Hey now!  Before the contest you said that this would be EASY for you

well, beating the game and not dying is kinda easy, but beating every freaking level and not dying - that was a first for me

No, I think you specifically stated that you could easily beat every level with one life

I'm glad you lived up to your tough talk

wow, you're right. don't know why i put every level on there . I sound like a jerk there

Anywho, I've never beat it all the way through, beating every level without dying until this run. Sorry if I sounded like a jerk in that post - I have no idea why I said that.

Oh well, it applies now , not that it's easy.

Congrats to Dr. Robbie, you came up with a pretentious idea and finally achieved it in the week, that's bad ass!

I knew someone would probably beat my score, I'm really no SMB 3 expert, I simply put a few efforts in the contest. I'm still happy to get the 2nd on this classic NES game.
