Tsk... I watched let's play about this game long time ago, and I remembered everything I watched in the process of playing the game...
Nice trolling, memory... now I can't play this... it's pointless...
Also, this game... it's like dev put too much effort into it.
Good
1) Animations are good.
2) Sounds are good.
3) Graphics are good.
4) Levels are fine.
5) Atmosphere is good.
But... there is a lot of ruining effort as well.
1) The amount of text and dialogues for an action platformer metroidvania is... too big and there is a lot of pointless text and dialogues.
2) And it would be less destructive, if most of the text was not voice acted! I'm trying to quickly read the text, but hearing some voice in the background makes it difficult to read. I can't turn it off, because it will also disable other character voices.
*sigh*
I think this game would be totally fine with only story related dialogues and golden computers. Though I didn't mind mocking if someone sucks at boss battles...
How to balance gaining behavior points? It would be better without it IMO, because making it pain in the ass, and balancing it pain in the ass.
How to divide game into different endings then? Just reduce game into several important choices, like you already did with helping red haired girl or not.
Many useless items. The only ones I find useful are just damage amplifier, damage reduction and... vibrator... healing item.
All in all, interesting idea but bad realization.
