This level's part of my newly finished series, Mega Man World! (I might miss saying this- Yes, it's the same name as the Gameboy games- Well, in Japan.)
Here, you're at the apex of Wily's Castle, ready to defeat the villain at last- but the castle... Seems to be rising! Time to defeat Wily once and for all!

This is the final level in the series- so play the previous levels first, if you want to play the series like a full game.

Bonus Comment:
I was in a panic to make this one! When I watched the trailer and learned 1.9.0 was coming out TOMORROW, I was like, ''Oh boy, I need to get this level done before 1.9.0's out...'' Also, that other level that I wanted to finish before 1.9? It's not coming before then. I still had quite a while to go, so I just stopped working on it. I may upload it in the future, just edited to end at the point I'm at, but, well, yeah. This is my second-to last level before 1.9. My last one will be a level dedicated to 1.8.0, and 1.8.4. I'm getting kind of emotional, because this is the last level of Mega Man World! Well, see you there.
