Toby Fox the creator of Deltarune makes clear through the whole game, that "Your choices donīt matter".
First by deleting the charakter you create at the beginning of the game and making "Kris" to your Vessel,then by not letting you choose the dialog in some places and finally by making only one ending to this Game or rather the first chapter of it.
