Think of it as an achievement =) The "static" germs I know are annoying and can catch you off guard the first time you encounter them. They get me quite often. So increasing the warning time before they do their power is understandable.

Haha they are a bit over powered. Would increasing the time before the connections actually activate (transition from a line to the static animation) make it more reasonable?

Also you cannot place objects on a rooftop. If you take a look at my property, there are two rooms that seem to be a rooftop, but are rooms using a low wall (which can't support a roof or room above)
