Being Addicted to Undertale Fills You With DETERMINATION.

Guys, guys, I finished Undertale! I did the true pacifist thing. :D It was pretty awesome. I like how it feels like an old game. And the music is nice too. Question about the end...

Spoiler:

I got to the end where everyone is waiting to leave the underground. So I went and did a last look through the underground to talk to everyone. Just wondering if there is anything else I should do before actually ending it. Do you have to start again after?

Nah, you're all set. Well done, you completed it so fast!

Now you can do a genocide run!

That's so awesome that you finished it! 8D Hoorah! You had to play through it twice though, right? :]

I looked up the same thing and found that you can go riiiiiiight back to the start of the game, back through the ruins to the beginning... It takes ages, but in my opinion, it was worth it to speak to Asriel there. Make sure you speak to him multiple times, though, not just once, haha.
