This level's part of my level series, Mega Man World! (If you've seen the other levels, you might know why it's called that. Not specifying it today, though.)
In this level, you've just exited the scrapheap, and you're now at the center of Wily's Castle. All of the Robot Masters from previous stages are here, so watch out!

Try all the levels in the series (With the Wily Stages in order) if you'd like to play this series like a full game!

Bonus Comment:
I managed to make this (and upload it) in only two and a half hours! Absolutely surprising! Granted, it was somewhat short. It's also the second-to-last level in the series. I still have to finish up a boss rush, but I'm almost done with everything I'd like to do before 1.9!
Mega Man Maker 1.9's release trailer is coming in about three days! Hype!
