I had a fun time playing the game and ended up spending a a little amount of time figuring out some strategy to it.
I figured out that you can interrupt an enemy's attack by punching them, and they will always attack at the same interval afterwards. Then, it becomes easy to time when to repeatedly punch enemies in a loop. This issue is compounded by the fact that you can start fights always landing a punch and immediately put them into this loop. I think this game is fun, but once I figured out the strategy, that's pretty much all I did for the rest of my playtime and it never failed once.
