Less than 24 hours since the mod was released and I've already cleared it on True Pacifist. This was a blast to play, watching Niko's responses to the characters and situations, and how we-the player-actually have a much bigger role in this compared to the normal version. Also, the fact that Niko interacts so much in this game gives me incentive to never do the genocide route. I refuse to hurt this precious cat-person.
Alas, it's not a perfect mod. Some of the dialogue from one of the enemies is borked. I can't remember which one, but I think it was a Waterfall or Hotland encounter. The text for one of their ACTs will suddenly shrink and stay that way until the start of next turn.
One of Asriel's lines when you're talking to him in the Ruins is botched as well. Specifically, "Niko... You and [PLAYER] really ARE different from Chara."
