Rumble mode: in some level in order to fight a boss of something you need to chase after him while fighting a gang of mobs. Sometimes you run away from enemies or bosses. Press Q for trail mode cuz why not? Press Q again for ??????. Press E to stop it. Pres H too shoot and J to slide W A S D to move Press R to restart. Your platform and hit enemies with your fist and slide. but really tho I think there should be some other things that make our game different from the other Undertale fan projects
