Ah, I knew it! When I reached the Nest part at the end, everything went so perfectly that I actually hesitated whether I should break myself just to try again!
I knew it would be difficult but fun, yet I couldn’t resist wanting to save the miraculous egg that had made it that far, so I went ahead and cleared it!
I went back and played that part again just now, and yes—it was really difficult! And it was so much fun, thank you!
