I was into the Spiderman runner for a couple of months, up until the Halloween event with jack o lantern then some crazy shi! happened to my account. I ranked second so got the reward but the game glitched on me, giving my account basically unlimited iso8 and the same reward like every other minute, plus iso. It slowed the game down something chronic so I had to uninstall. It was sweet having every character maxed out though.
I'm playing I Gladiator now!
