blue bones: stay still, they will damage you if you move. gaster blasters: they shoot lasers. avoid them. white bones: they will damage you. avoid them. orange bones: only damage you if you're not moving. don't press space. this isn't an easter egg, just a bug.
while the project isn't finished (and probably never will be) it's still super difficult even though i never added the rest of the fight .credit to @BAROQUES for the music credit to @Glitch_Brandon for the sans sprite credit to Toby Fox for the original Undertale game, and for the textures of the fight buttons, soul, box, and for creating the original sans character that this character was based off of. You'd have to known at least a little Undertale lore to understand what sans is saying, because otherwise it makes little to no sense and just sounds kinda cringe.
