Welcome to UnderQuark, the Undertale mod that makes some things quite different from the vanilla game. The name of the mod is inspired by the name of a Minecraft mod called "quark", hence UnderQuark. However, its development comes much earlier than its name. Apart from making things different, it also restores some unused features, the last is, however, not the main focus of the mod.
The first public version of UnderQuark (yes, there are previous versions not released to the public) Also called by me: The Frisk? Update. If you want to add more features to the mod in the future, please pu your thoughts in the comments.
