Another Super Mario Bros. Wii 100%: 9-7

Here's the other one I struggled with the most...just like the real game! But it's not as fun to watch the deaths, as it's quite long, so I spared you all this time. :)

The level is generally difficult. See the last set of tilt platforms - at one you have to jump to the right while tilting to the left, a very awkward motion. In the foggy areas you have to basically learn the safe spots, and mid-air spinning becomes a necessity toward the end.

As skawo commented on in 8-3, I guess a Propeller Suit cures everything, but that's no fun; I spam those next level. But the real points of trouble come on the star coins:

-1st: You can get up to a 17-up here, but most likely your greed will make you fail. Oops! Eventually as I piled up deaths
-2nd: This one caused me more deaths even in-between after I got well past this point (see the jump from 74 to 65 lives). It's crazy positioning and timing to catch the edge of it, sometimes a small jump from the top works, sometimes a high jump, depending on when you jump!
-3rd: Here's where I managed to make a bad mistake yet come up with the best save in my SMBWii "career". :P You're supposed to get this one going from RIGHT to LEFT, and do a couple of mid-air spins back onto the purple platform at the bottom. This cures jumping right into the wall going from left to right and falling short. But again, I got out of it!

Good luck if you're doing this - longest non-midpoint level!
