Green flag to start. arrow keys to move around. H TO PUT ON EXTREME MODE(don't do it when sans is talking or it'll mess up the gameplay)
Sans is trying to give YOU a bad time! make sure you dodge his bones! *Health reaches 0= YOU LOSE! *Time running out= YOU WIN! by the way please report bugs in the comments ^.^ Note: IF YOUR HEALTH IS GOING BELOW 0 AND YOUR NOT DYING RESTART THE PROJECT. Also, if this is to easy to you, try EXTREME HARD MODE (maybe impossible mode) WHERE GASTER BLASTERS START SHOWING UP. you only need to press h for it to happen. Oh and the bones used to disapear when the gaster blasters where gonna fire but it teleports the bones to the corners and i couldn't fix that update so now, its basically a lot harder.
