(recorded with SNES9X 1.51 + v.6)
My comments on the levels of this speedrun:
Pipe Mountain: Nothing serious here, used the 6/5 speed trick on the whole level. The pipes skip part was a nice but very simple.
Grisba Chucks: Using the Yoshi was pretty useful here, I just skipped a pretty big puzzle part with the Yoshi-drop jump in the dark cave.
Donut Lift Town: Two walljumps in this level, and both were quite useful. With the dark Bowser music level I skipped a relatively long puzzle part again.
Emerald way: Minor skips here.
Iggy's Castle: Nothing serious here, at least I could play around a bit in the scrolling part.
Marble Valley: To be honest, I still don't know how to do that part with the walljump (outside) without a shell or a walljump. =P I quite broke that little puzzle part in the cave though, I think. And finally got a cape!
Doneky Ruins: Minor skips here with using the cape. Btw, this level inspired me during making my Big Boo's Legion 2 level, Mysterious Shrine. That's true!
Sunset Run!!: Nothing serious here, but really. Just flying.
Marble Angry Zone!: Damn, I noticed that badly developed swimming only after I recorded the whole video. =/ I'm really sorry for that. Fortunately it's not too long. At least I could fly under the ground in the later part.
Larry's Castle: That weird layer 2 scrolling part was very interesting to beat, but I think it isn't too bad. Other than that, nothing serious in this level.
Enjoy and comment please.
