Devil May Cry's first boss completely slaughtered me, and on the occasion I beat him the side mission would cheese me off.
I actually beat the optional mission on my first try but then for some reason erased my original save. I was never able to do it again, and couldn't consistently beat Phantom. Ahahaha~ at some point it enraged me so much that I couldn't even consistently do something I'd done before (and in the side mission's case ever do again) I broke my fancy new widescreen TV over it. :'D
I have since unlocked easy auto, which makes the game so mind-numbingly boring it's not even worth the time anymore. thing plays itself.
All of this could've been solved by making your controls make a lick of sense, Capcom. X is jump. the bottom buttons is always jump, and has been since Super nintendo. Not "pull out your guns and slow to a crawl while what you were trying to avoid destroys you." Never could get "TRIANGLE NOT TO DIE" into my head, for some reason.
Stupid game. ._.
