Awesome Music: Music in a fanfiction? Well, sort of. The author suggests playing WilyCastle 1 from Mega Man 2 during Rock's first raid on Skull Castle.
Growing the Beard: While the first two episodes are good, the story really hits its stride with Episode 3, exploring more emotional territory and providing its own spin on several episodes. Episodes 4 and on continues this by starting to tie the subplots together and introducing new takes on elements from the game.
