This game is THE BEST! Smashing through zombies, earning cash and getting cars. But the game might take WAYY too long to complete unless you keep spamming the ad for cash button and getting the money you needed. I wouldn't say that there are too many ads because I kept on watching ads for money XD. But I would usually say 10% of the time I play comes up as random ads. Nice game from your fan in Sydney, Australia :)
