Knytt Stories - Tomatoes! Gaiden Partially Blind Playthrough Part 2

Found some secret content and got another ending.
I assumed this was it, but a glance with the level editor revealed there's still plenty more. Not feeling like going through that right now, though.
Edit: This playthrough won't continue. I tried searching for more content and was forced to conclude that the next notable challenge is god-awful. I don't know if Wibi is the one who came up with it, but after being forced to give up on finishing or at least fully completing every level they were involved with that I ever played, I'm never touching anything from them ever again.
