As "stolen" from  shalonesk ( http://www.furaffinity.net/view/1030150 )

Yes, bitches. I went 100% OLD school - Commodore 64 + 1541 5.25 inch floppy disk drives...

(VRRRR.. ti-tick - ti-tick - titick....)

Object of the game is simple... you start out somewhere in the Continental US with 10 diamonds - you grow more by putting them on the ground and letting them multiply.

You have to find the mutant TV, called the FuzzBomb somewhere in the USA. As normal people touch it, they're drained of thier diamonds and turned into FuzzHeads - who will drain others of half thier diamonds until they become FuzzHeads too.

You have normal local trains and rocket trains to help get you closer and closer to the Fuzzbomb. Touch the FuzzBomb while carrying 100 Diamonds and you kill it and turn it back into a normal TV again.

BUT... get hit by the FuzzHeads too many times OR touch the FuzzBomb with less than 100 Diamonds.. and you become a FuzzHead too!

The previous version got compressed like crazy... so modified for legibility
