Great time killer but I've kinda go bored of it now that basically the combo doesn't stop increasing, I've just left it on its own for the past 20mins or so and the combo meter is at 2 million and is still increasing.
Good game a bit on the easy side once you get used to the controls and the different cell types, I preffer using a combination of x2 rep and x2 strength. maby if and when you create another sequel create differnt difficulty levels
