Cheers. I did have one spoiled that you might be referring to when I was watching a video today on my lunch break that was meant to be just about tips. Without ruining it for anyone else, in chapter 2 it was collecting eyes and summoning a second boss for a particular fight. The first eye is easy to stumble across so the game is already hinting what to do.
This game is very good at hiding secrets in plain sight but make them so easy to overlook. Even the headless singing man is giving advice when you stop jiving with his tunes and actually pay attention to the lyrics.
Not that boss, but that one is essential IMO.
