This Super Mario Maker course is still torturing me

Yesterday, I posted a video of me discovering and then failing to beat this incredibly difficult Super Mario Maker stage. Today, I went back for more.

The stage is called “Underground Spin,” and it is a Super Mario World course that requires several perfect spin jumps that make you invulnerable to certain enemies. But this stage also has secrets that you have to uncover to beat it, and I only found a few of them today.
