This mod is my answer to a question that I (and I'm sure lots of other people still have): "What if Deltarune was ACTUALLY a sequel to Undertale?" While this mod doesn't change the general gameplay of Deltarune, several other aspects have been changed to give the game an Undertale feel.
Example gameplay image: the full party fighting the "King of Spades".
