I have to agree with a lot of the comments below. 3x speed just doesn't cut it. It feels like that's the pace the game should be on anyway. Certainly none of the events are unmanageable at that speed... Give us 10x!
I've a problem with the game. When I get to the volcano level I don't get anything but blue polyps and only red and yellow planty things. I can't get anything going! No completion possible. WTF?
