@not-Celeste Hey! Sorry I couldn't answer right away!
Sorry, but I personally don't like Undertale or Deltarune, although I am in love with the music (Megalovania, His Theme, Undyne's Theme, etc.). Although, I can help you with the basic plot and how the story should lay out, if you'd like!
Also, sorry if I'm bad at explaining this or get something mixed up, I don't exactly like the idea of putting these two together, but I'll try my best to help a friend out! :)
Uhm... Well, use a variety of words. This goes for any book. When you're writing a story, it's those 'Big words' that hook your viewers and make them more interested. I suggest -- and use -- a thesaurus every time I write a new chapter. It doesn't matter which website you're on or in what context, they're extremely useful.
For example, instead of putting,
"Yeah, I'm doing great!" Tom said.
Use words in replacement for 'said'. Said is a commonly used word for thousands of writers, an it's alright to use it occasionally, but don't use it as often. Instead, you could use words like,
'Exclaimed' if Tom (or whoever else) is happy, excited, or exclaiming loudly (If something were to happen that would make 'Tom' yell, whether happy or mad, this word is effective). If after writing your chosen character's dialogue and you notice an exclamation mark/point (!), this word would be great.
"Yeah, I'm doing great!" Tom exclaimed.
Sounds much better, right?
Also, don't forget to list the main character (the character the you have the perspective of) to show their reaction, not just through dialogue. For example:
"Yeah, I'm doing great!" Tom exclaimed. So loud that, I jumped and almost fell out of my chair.
Also, add some, but not too many, random things, like.
"Tom, could you keep it down!?" I'd hear the teacher yell and gulp. "We're writing a math test!" Man, do I hate math... etc.
Sounds good, right?
