For the base game, none of the bosses are soul crushingly difficult, but there are a few that may take a decent number of tries. Honestly getting back to some of them is the bigger pain than actually dying. Luckily there's a way to shorten it at least later in the game. If you want to 100% the game, the difficulty goes way, way, way up. For difficult platforming, there is the optional Path of Pain, and it is not a fucking exaggeration.
