Ok
I'm confused what the "true ending" is. Is it the one where you hang out with everyone? I know for sure I got the Undyne neutral, but I don't know the ending I just got... Help!
If Sona takes control of the game is a Neutral ending.
If a monster fights Sona is a Genocide ending.
If they break the barrier around the city is the true ending.
If they break the barrier AND everyone survives is the truest ending.
