This is the current hardest level I've cleared in SMM2. I won't go into too much detail on the grind because it was probably the unluckiest experience of my life, but it took 4 painful yattenais until I finally uploaded it. Compared to other insane levels I've cleared, I believe this is harder than FF4, and even rivals Magnum Opus
