i put this post in my favorites, will read it after mypacifist run (but i'll do first the genocide run, i already did a lot, would be a waste to redo it laster, too long to kill everyhting... after all you're not supposed to know everything that will happen, so if it ruin the true ending, so be it)
Yeah, definitely do that. Sorry for writing it down already. I was kinda anxious about mentioning the Genocide thing or the other thing, but since you talked about looking on YouTube or getting someone to tell it here, I figured you might as well do that if you are being curious.
Either way, yeah, you're better off only reading it once you're done with that stuff. Have fun with Undertale.
