GIRL BOY --BANDAGE GIRL ONLY-- GET!!
Oh wait. You're only allowed to use Bandage Girl... I'm too used to the idea that using one character is unique! Oh well. Here's how I did it!
7-7 - THE FANS. Enough said. I increased my probability of success by approaching the first fan at a walk and pressing the run button to start moving when I thought I had just enough speed to miss both middle saws... but it was mostly intuition. I reset this level so many times in mid-flight, but I did it on my first try in the run, so I'm happy about that :-D.
7-16 - F***ING HOPSCOTCH. I have no real advice for this level. It's so early in my run because I'm absolutely terrible at this level. If anyone has any 'tips' that'd be cool. But I'm pretty much going to get a halfway decent speed run time and forget this level ever existed. Ever.
7-19 - It's levels like this and the next one that prompted me to vote the way I did in the "most hated obstacle" poll. Small corridor saws >> Demon Maws. I beefed it on the last saw so many times :-/.
7-20 - Two reasons I put this early. First, I would not have the composure for such a long level if it were near the end of the run. Second, SMALL CORRIDOR SAWS. They make me shout many four letter words (har har).
7-15 - This is why I think Demon Maws are a pushover. This was, for about 15 minutes, one of my major concerns for this run. Until I completely TRIVIALIZED the level. The start is important. Jump right and wall jump just after you touch the key (don't touch the floor). Wall jump two more times (three total) and on the last one hold left. You'll slide down the wall and avoid the first Demon Maw. Tap left again to get on the platform with the key. Jump right, touch the wall and IMMEDIATELY jump left. The Demon Maw on the right will slam into it's little niche. Idiot. Wall jump on the left wall twice and move to the right wall. Slide down into the right Maw's niche. It will slam into it's own wall just before you get there. Dumb ***. Grab the key and immediately jump left. The top AND the bottom Demon Maws will slam into their respective walls. Ha ha ha. Jump right and wall jump into the second section.
Keep close-ish to the left wall when starting the second section. Hit the ground and run to the key. The Demon Maw will shoot over your head and hit the locks. Grab the key and jump over the mini-maw. Get to the left wall ASAP. If you go fast enough, the spawner won't "see" you right away. Slide down and tap left at the opening to DI into the key. Run across the keys as they disappear. If you time it right, the Demon Maw will slam into the locks and you'll fall through the unlocking locks before the mini maw gets you. Repeat this process again (slide down the wall, get the key, walk along the locks and drop to avoid the mini maw). When you've unlocked the last line, you'll drop and hit the wall to avoid the mini maw. Wall jump to get to Meat Boy.
I may try to make a video of this later.
7-5 - I just didn't like doing this level in the later parts of the run. It gets very difficult if you're nervous.
7-2 - The timing required to not get hit when transitioning between the top and bottom corridors was kinda funky. So I put this early on.
7-10 - There are a bunch of keys here, but it's symmetrical so you only have to accomplish three tasks. Getting a low key: I ran from the middle cover all the way to the wall and slid up past the disintegrating blocks. Both missiles will miss. Go into the corridor and grab the key. Run back to cover (when in cover DO NOT touch the back wall, you'll have gone to far and a missile can hit you). Getting a high key: run from under cover and jump so that you wall jump twice to get to the high key. Grab it without touching the back wall and short hop out. I liked adding the short hop, it raises the missile trajectory just a bit before you drop down to cover. Escaping: run out of cover on the right to attract the fire of two missiles then run left. Wall jump once on the bottom wall, TWICE on the middle wall and on the second wall jump move to the top middle platform. IMMEDIATELY jump to avoid the incoming missile, get meat boy.
7-11 - This one is easy. I like to get four missile shots in before jumping is required. I make the first two jumps while still progressing forward. Then when jumping over the saws, I alternate dodges - missile hits behind me, then one in front of me. This pattern repeats three times. If done right, dodging the dropping saws is easy. A video may be required here to explain better.
7-17 - I found a really easy path, but there's no way I'm getting the point across in text. Maybe a video to come? I have to figure out how to get good videos going :-/. Maybe replays will record easier than playing in real time.
And that's it. All the other levels were easy. I think this was a little easier than doing Meat Boy only Zombie Boy. And as per usual for my "investigation run" of the next achievement in line... Impossible Boy does indeed look... impossible!
One down, one more to go!
