What differs the game from standart click&upgrade games is that you see the upgrades change the landscape of planet in addition to generating points.
What makes it bad are hardly understandable upgrades description (I mean, you don't know how much it generates until you buy it), popping numbers which doesn't correspond to actual gain and lack of any sound. Also you just have to be into this kind of games to enjoy it, it doesn't have much else to offer.
Help page couldn't offend me, because it just perfectly described what the game is about.
And about Cells upgrade, the problem is it always costs 15 points no matter how many you got.
