You walk over to a strange booth and talk to the attendant. He was around 10 years old, but had a look under his black cowboy hat that just screamed "no insults or else."
Y:excuse me?
T:name's tom. Gimme 5 bucks and i'll let you play.
Y:what is it?
T:You just shoot the orbs. they have strange effects. But I can guarantee you you will still be able to hold a gun afterwards and won't turn into a girl. And you'll be alive no matter what. Age progression stops at 28, regression at 2. The gun part might get a bit tough though. oh, and some require another to activate. at the end, all the effects happen. And your clothes change to work for ya.
Y:which does what?
T:Can't tell ya that. But the effects are the same for each color, and whichever one does one thing, the opposite does the opposite. the blue one does the opposite of the red one. but once you hit one, its opposite becomes rarer. that is, if ya dont like it. and they sense emotions.
thinking it's a joke, you hand him the money and prepare to shoot. he hands you a pistol which looks like it belongs in a western. you aim, and see several orbs come up.
