IMPOSSIBLE BOY GET!!!
Check out the video! Details regarding my run will refer to it :-D.
7-7X: I used the tap right and jump technique here. Credit to Zip_00 for that.
7-8X: It's just a matter of good timing.
7-9X: I used a mark just below the top of the salt mound to show me when to hold away from the conveyor belt. I would look at the salt mound, trace the line to the conveyor belt's arrows and pick one as a reference. When I got off of the belt, I was NOT holding the run button. That would help keep me from going out of control.
7-1X: This is here because I'm bad at the saw jumps near the middle of the stage :-/.
7-19X: Walk, don't run. It makes this so much easier!
7-20X: So long as I made the mini-saw jumps I was home free on this one :-D.
7-13X: The more I did this level, the worse I got at it, LoL. It used to be the last level in the run, but I had to bump it up so that I didn't mess it up while nervous.
7-16X: My first reset is here. I didn't time the first jump right. But outside that, my consistency for this level is definitely accredited to bullexcrements. Thanks a bunch!
7-5X: This was once the third to last level. Until I lost while doing it. So now it's here so that the end feels more "home free". Just like the purple blob level in the Cotton Alley Light World, I just had a hard time doing this one under pressure. It's not inherently hard.
7-6X: Extend the first wall slide as much as possible for great victory!
7-10X: Used to be near the end of the run too... but I lost a run here as well. So I bumped it up. Not that hard once you get the pattern down.
7-14X: If you stop on the platform before the key, then running through the key is OK. Otherwise slipping off the key platform is likely. I tried the walking method, but I would jump off the key platform and slide up the wall that housed the middle laser... and die. After the key I jumped into the platform on the corner because I found if you stand on the platform just before that, the lasers sometimes clip you. If you go to the corner, there's zero chance of them doing that.
7-15X: Not too hard, but the jumps to get to the waiting area have to be very very crisp, otherwise you won't make it in time. I tried to do the multiple wall jump method (instead of sliding up like I did) and I just couldn't get that timing to work as consistently.
7-17X: That's the pattern I used, it's not too hard to pull off. :-D
7-18X: I reset here. It's the last time I reset too. I didn't get the wall jump to work. Anyways, the key here is to get them circling you. If you can get the pattern working on small groups at a time (instead of herding them all at once), it's easier. The run seems to get crazy at the end, but I had full control. Weird, right?
7-2X: The transition is somewhat difficult at first. But outside that, it's patience and good timing.
7-3X: I pretty much know I'm home free at this point.
7-4X: I like this pattern, the jumping rhythm is pretty consistent.
7-11X: Easier than my first pass of this. I was worried about this at first, but once I got it down, my consistency reached better than 95%.
7-12X: To me, this felt like the victory lap. This level is very easy. I passed it the first time I ever tried the Cotton Alley Dark World, and I do not believe I have ever died here. It was all about keeping calm and getting my achievement!
That's all folks! I hope you enjoyed all the meaty goodness! If people express interest, I may re-do some of the other runs using all meat boy. I'll also do videos for certain levels if anyone wants any visual tips on how I did any of the runs.
Until then. I'm done! I *might* speed run a bit, but for me this achievement is pretty much the pinnacle meaty goodness :-D.
All the best,
