That's Bosses in games in general for me. I hate them. Always have
I am generally the same, unless it's a particularly interesting boss set-piece.
However, played CupHead co-op with a pal the other day, and the boss-rush levels were so much more enjoyable than the trad run and gun sidescroller levels. Really intense, but satisfying to beat and was happy to try and try again. Suspect my patience would be greatly diminished, playing solo.
