I'm a hacker, I can make you disappear in this game with the snap of my finger.
The authorities can't do nothing about it since they can't see me, so much as acknowledge my existence (ingame).
I can modify the game data at will, so basically, at the snap of my finger, you'd forget everything (ingame).
Hmm, what if I wanna fool around and tweak the gravity to 100 (default of 700)?
JUMP! JUMP DANGIT! Oops, I set it to 1000 instead, sorry about crippling you.
