just download the spritesheet. it should be a .png image. btw if you are considering using these for whatever reason no need to credit me.
all sprite credits go to deltarune. i ripped these sprites by extracting deltarune's data.win using quickbms, and using piskel to place the sprites in an individual frame. i then organized the sheet a bit. and yeah, there are a few unused sprites in there. look very ugly and ms paint-esque, don't they?
