Just wondering what people would consider to be glitches in this game. Obviously the dead alive and out of bounds tricks would be, but do people consider the cutscene skips to be glitches?

Personally I think they're just exploits, but I'm kinda torn when it comes to the Korenchkin fight skip. I want to add it to my glitchless route but first I'd like to hear a consensus. It's really just hopping over a trigger, but skipping an entire boss fight is pretty huge. Thoughts?
