Thanks for the compliments. I did fear that maybe it'd be too hard for people, but it's hard to tell that kind of thing yourself because it's always easier when you're the one making it. Maybe it's easier if you know that dodging and counterattacking immediately afterwards is the key to getting lots of hits in? Plus knowing exactly how many punches you can get in after each dodge. Who knows.
As for it being a puzzle fighter, that was partially the goal. Figuring out the right way to attack is part of the fun of Punch-Out!!, for me anyways.
I'm glad that you enjoyed it!
