Moving holes

Right now, holes always stay in the same place of the grid. Would it be hard to make them follow the trail forward at the cycle's speed? On the same topic, I've heard people talk about wanting shrinking/growing holes too.

Yeah, both would be pretty hard. Hole datastructures are optimized for stationary holes and so they can handle big holes that blow away whole wall segments, and many of them, well. Moving holes are in a separate leg of possible optimizations, there probably isn't any good way to get both.

Shrinking holes is really a great idea.
