As soon as the final boss was confirmed as polygon man I stopped caring entirely. So not being able to attack him doesn't even bother me.
If it was a cool boss, like Dr. Nef, I'd be like AWWWW WHY!!!! But this boss was weak anyway, it's probably better to spend as little resources on the fight as possible.
Well Polygon Man is a cool concept. You can't just say he's bad because you hate him. You can't blame them for not wanting to make a boss out of 20 game villains or picking one over the rest. He is a cool character though, if I had to pick 1 it'd be Colypso or Specter.
