Ok, here is what the books do. Harry potter books allow you to fly and shoot down planes (to gain more points). Twilight books turn you into a wolf, which doubles your speed, and make you immune to obstacles. You still die if you fall of the building. Jaw books turns you into a shark, where you have to feed yourself while avoiding mines (the area also floods). If you crash into an obstacle (except werewolf), you will lose some of your transform time. If you collect books corresponding to your form, you gain extra time (and also counts to filling the transform bar). It appears you cannot use a form if you fall off a building, so use them as soon as you get it. Hope this helps

Oh come on guys it was made in 48 hours. It's pretty good although it's largely a reskin of a different, whole lot worse game they made.
