I finished this game with both the continue cheat, and savestates- and using them made the game a whole lot more fun to me. This game is hard, in the arcade sense of the word- limited lives, unfair on-purpose enemies, and level design.

I had fun, but the movement did have its shortcomings. Overall I liked it, I like knowing that I've actually played this important game, but playing 1.1 is all you really need to do here.
