White Knuckle: Beating Body Cavity AGAIN because for some reason my save reverted.

Yesterday when I beat Body Cavity and unlocked the Rotten Duct, I closed the game when I ran out of all but one life cause I was tired and too anxious. Today I opened it up and found my save still there. With all 3 extra lives I had. And all the items I had before attempting Body Cavity. And with the Rotten Duct locked again. So I had to do it again; and thankfully did it first try. I had started recording once I loaded in cause I found it weird that I had a save when I should've had one when I got on. I also recorded all my deaths after beating body cavity, I wasn't taking the game too seriously and I think the double jump perk hindered me more than it helped me due to the stamina drain.
