     Well, my first big game release, how do I count the ways of impact?  Speaking of impact, Doom
 has quite a bit of it.  Where else can you run, blast, and bewilder yourself through ten, count em,
 ten levels of utter mayhem.  I assure you, the game will be fun, or we'll unleash a vortex in your
 home.  In any case, I must pay homage to DoomRater, from whom I obtained the engine and
 manipulation codes for it.  All in all, I must depart, stupid vortexes, so have fun, and keep on
 fraggin!
                                   Thanks,
