Well, i've just finished all the routes, pacifist is fucking awesome, this game is fucking awesome, and while i do regret killing all those awesome characters, i don't regret doing genocide route first, by finishing genocide i got through the hardest part of the game, the biggest challenges it had, so then i could really chill and enjoy the pacifist route (i did a true reset btw, yes, i CAN get over consequences with the knowledge of the AppData folder), and i spent a damn good time interacting with every character one could talk to.
This game's huge and awesome, it really made me feel all kinds of feelings, and i'm glad i didn't neglect myself from any routes, seeing the game's entire contents feels pretty achieving.
