I did it! I also checked and confirmed with the Wiki that I got the pacifist ending. :)

Thanks for the tip earlier!

Spoiler:
Holy crap, that boss battle with Flowey is one of the most deranged gaming experiences I've ever dealt with (and I have seen a LOT of weird crap pulled time and time again that messes with the player's mind). And that part where you get kicked out of the game back to your desktop and restart it only to have even MORE screwy things happen was not something I expected either. I first, I thought "crap, probably need to do something different next time" and then that happened, followed by even more crazy stuff.

That ending was great though and you can't help but laugh at the dialogue and goofy jokes the characters throw at each other. Watching Papyrus drive a convertible down the highway with Sans on a motorcycle next to him was priceless. XD


Seriously, thank you all for pushing me to give this game a go. It's been a definite treat. :)

Now I can see why someone told me attempting the Genocide Route means "you're gonna have a bad time."
