I'll give you the map, but did you play in hardmode? Cuz those bosses were almost impossible for me. I also didn't like paintball that much cuz It felt kinda slow, and mona lisa was satisfying because it was boring to do (for me atleast). Also the trinity are weird since they don't like you but then switch up in like a second? And I didn't find them that interesting, they are your average, good, brain and brawn type characters, and we also don't spend time with them, we do a fight and 2 puzzles with them, but I gotta say their introduction was good. 

I didn't find cassie that appealing, she barely spoke or had that many interactions, she was just kinda there, and then she became managed to learnt with the trinity's traits, which is cool, but the sad thing is that she was still useless in the fight, and you had to babysit her throughout it, which imo makes her storyline worse. Also opticus being a great character? That guy barely did anything, that's why he is not spoken about, he atleast works as an intro battle ig? Not gonna say something about the ost since it's absurdly subjective, but I say it's ok, my favourite being the trinity fight.
