I've played the original one on the nintendo switch online nes service and I must say, I was pretty bad at it... I'm still pretty bad at it. It was a lot harder than I thought, and I eventually go to beat Mr. dream... by rewinding every second.
I'm playing this occassionally, yeah the Mr. Dream classic, it's pretty fun. Just fought Piston Honda, and gotta say, he looks Pis't! He beat me the first time with that flurry of punches he does. Which brings the question, what is the best way to deal with those? Dodge left/right, guard, or duck? At any rate, I beat him the second attempt by trying to duck his flurries.
I found it silly that he mantras random commonly known words like Sushi and Kamikaze inbetween rounds. He also makes a pun with "TKO" but i forgot what it was :')
Having lost to Piston once, and watching his victory animation, makes me want to lose to everyone once to see their victory animaniations too
