Good morning/afternoon/evening, depending on when you see this message (if I'm lucky enough to read another one of mine), I wanted to ask you about adding "mods" to the game. I want to create a mod for Ponyvania, since it seems it won't be updated anymore (with new content like bosses, enemies, areas, etc.). I wanted to create a mod to offer a new experience and places to explore, but the wiki mentions something called "undertalemodtool" that can modify the game. I tried it, and it's very complicated, even changing the sprites. I wanted to ask if there are any good alternatives for creating a mod that adds new things.
(Something I want to emphasize is that I'm not trying to steal the game or anything like that; I have a lot of respect for this game and I don't see myself doing that to a game as good as Ponyvania.)
