Twilight has been theorizing about alternate universes for a while now. One day, she finishes developing a spell to send her to a different world. She decides on a particular universe, based off of a video game she's been hearing a lot about. When she gets there, she manages to strike up the most unlikely friendship she's ever attempted.
First of all video games do not exist in Equestria you're story would be more interesting if Twilight didn't know about undertale

Sorry for the late answer and thank you for your input! I appreciate the feedback. I agree with you that it could be more interesting, but the entire story is just a silly thing I wrote for fun, so I'm not really worried about it making sense or being very coherent. Also, this takes place far outside of canon, so it's perfectly possible that there are video games in this particular version of Equestria. I don't think that small of a change is enough to justify the AU tag on the story, though. The same goes for Undertale in this story; some things are going to be slightly different than they are in the game, mainly to carry the story along and help readers not get confused.
Thank you again for giving me your opinion on the story, and I'll be sure to keep it in mind while writing the next parts (and maybe editing previous parts, if I feel like it). And of course, thank you so much for just reading the story! I hope you have a wonderful day.
How does she know that? Did I miss a prequel or something?

Sorry for the late response, but I'm happy to explain!
Twilight already knows about the fact that Undertale is a fictional universe through a certain friend of hers (explained in an Author's Note for a later chapter). She wants to talk to King Asgore, who she knows exists through the aforementioned friend, instead of Ambassador Frisk. She is also assuming both Frisk's gender and age, which is a little bit rude, but at least she was right on both accounts*.
*This is not to say that guessing right is an excuse for assuming gender or age, just that she was right to a surprising degree.
So, no, you didn't miss a prequel. It's actually my fault for not making it clear, so I'm very sorry for the confusion! I'll try to keep the narrative less confusing later on, though I can't guarantee that I'll be going back and editing anything, especially in Act One. Thanks for reading the story and pointing that out! I hope you have a wonderful day!

Well, there's your problem!
To make it short: the reader must get the story from the story itself, not from the author's notes seversl chapters later. You should edit the chapter to provide context to the readers.

Thank you for the tip!
I didn't really think the information was all that important, considering this is just a silly thing I'm doing on the side. There's also some hints towards how Twilight "knows" certain things about Undertale in later chapters, mainly (with minimal spoilers): in one chapter, a reference to MLP: The Movie and, in a different chapter, a reference to Alphys' Lab from Undertale.

Information is always important. Here's another tip: put yourself into the reader's place. Forget everything you know as a writer of the piece, and go through it and see if it makes sense.
Alternatively, find a beta reader.
