I can't continue because my last save file is corrupted, and I don't want to start all over again because this process took me two years.
All I can do is cry and think that 0.27 ended there.
You didn't happen to keep your old folder did you? I usually keep mine until I at least beat the new update so I can have my old www folder in case of issues. Never had an issue yet, but you never know.
I could maybe even send you a save if there's a way we can figure that out. I like to think I found all the secrets, if so I have a save that's a current full clear and maybe one from last update the same way.
At the same time, I don't think it would take 2 years to play again ha. Once it's fully finished I intend to do a full playthrough again
