First, I started file D and I spammed Z to go through the signs and I broke the blocks leading to the water and I did a triple jump and got hover nozzle and I went to the castle, skipped some cut-scenes and I did a triple jump at a wall in the room before the basement to fight Bowser in the Dark World. I used the secret pipe near the beginning and went to the Bowser battle. I think i died there 1 to 2 times and I defeated Bowser. I went to tutorial 2 and and unlocked the turbo nozzle and the rocket nozzle and used mostly the rocket one in the level and then I finished it. Then I went at the room before the upstairs key door. I did a triple jump towards left and entered a star elevator and I used the rocket nozzle before I entered the room before the up stairs key door and I used the rocket nozzle and I accessed Bowser's castle and i used the rocket nozzle to go through the first part and I used it again to get to the up part and went through the rocket nozzle way. I might have died in it twice and then I entered the door in the middle and I might have died in it 2 to 4 times. I did the fake final boss and finished him with out dying a single time and I went to the space part and I died in it 3 to 4 times and then I defeated the true final boss and I died in him twice and did the running form the meteor part without dying a single time and I finally finished the speedrun.
