You can also use the keyboard ("M" to attack and "K" to get your knifes back). The mouse is the only one displayed because most people feel more comfortable using them instead of only the keyboard.
appreciate you putting this comment here. You should put these keys in the options/tutorial. Since the mouse direction has no real impact on the knife throwing, it's frustrating to use the mouse. Also allowing "up" or "w" to be jump would be amazing.
