Sans Controls: use W, A, and D to move. Chara Controls: use Up arrow, Left arrow, and Right arrow to move and press Down arrow to attack Sans has had enough of your endless Genocide routes and has leveled up. Remind him who is the one in control. =)
All the controls are the same as all of the other two player sans fights, have fun playing, this is my first game (technically a remix) but enjoy anyway.
