At the beginning, all is fine, and its fun to play. But once costs for upgrades and structures go up, its a waste of time to spend three hours on the game. My story goes like this: I go on at first and enjoy it immensely. Time goes by, and I decide to get the auto clickers so I wouldnt have to spend all my time tapping the cookie and waiting in game. I maxed out my auto-clickers, and went into a spell that for a couple months I didnt even open the game. I come back with a huge amount of cookies, and in less than 30 seconds spent it all on upgrades. And then, I really cant do anything with the game. In conclusion, I think that though its fun at first it comes to be a waste of time.
