Green flag = start Arrow keys = move Space = continue if you don't click Z at the start to start, the game won't work.
Credits go to Toby Fox for making the original game. When in battle, dodge the white thingies. thats how you survive. when in battle with Sans, its impossible to survive. let me know in the comments if i should add more! I put this way down here because it's a secret ending. press space after you die.
