I finally got around to finishing this video! As to why I didn't do it sooner, that's gonna take a while to explain... To make my long story short, I'll just say that I didn't have too much time to play/wasn't feeling well enough to play and when I did play, I was doing terribly and when I did well throughout most of the world, I would miss the key or start messing up a lot at the very end, which only made the video much longer than it should've.
Anyway, I think I did much better in this video than I did on my previous attempts, which is what I was aiming for. Today, all of my previous attempts but the first and the second to last were pitiful and I don't think it would've been a good idea to show a video of myself doing that badly for such a long period of time since, if I were the viewer, I'd've stopped watching long before the playthrough were even finished.
