Yay! Wow, this one took a while, but it turns out Wily was pretty much a set of gimmick bosses.
So, some Wily stages. Nothing of real note (but next time, it should be completed!)
Finishing up the Cossack Stages…which were pretty short.
Into Cossack’s castle, I guess!
I blow through the other 4 bosses in about 20 minutes. Scary efficiency!
