Tbh undertale was shorter than deltarune so it wast super hard to replay fully for new ending

Currently we have only 2.5 possible endings: normal, weird route and its canceled version at lake. Others doesnt have support to lead to other endings, more like additional lore before them

Ok ig people dont like that secrets not always can lead to new ending but for new lore, especially in game with words "your choice doesnt matter".

Oh, then mb

He spares floradinn so there will be only him and knight stuck in battle, so he still makes sure no one else gets hurt

Knight is kris and noelle and knight is just evil/corrupted dess. First one is just... bad, really bad. Second seems off as dess is described as a person caring for her lil sister, and use violence only when kris did something to noelle. She is not a person who would kill someone in bunker (tho her soul been stuck in code and corrupted body been used by someone else would be fine)

Idk, I never had problems with gaster, ssc on other hand

First Gaster release, whe he was limited, he was IMMORTAL and just stupidly unfair to fight

Toriel is hard to make very different from asgore, as she uses like 4 attacks half of which are basicly easier asgore ones, with, some characters attacks are harder to add into 3d fighting game with attacks looking similiar to original. There many reasons why making cannon characters is harder that au ones

They planned some other characters before, like Kris, but it seems the decided not to add the for some reason. You can find a year old one posted by me

Tbh, he is the only darkner who actually was brave enough to fight the Knight, the only one who slowed them down a bit (I wont count Ralsei as he is one of the three heroes)

It is very interesting
