Yeah, I can do that much easily. It's getting the drop I send into the trench back to be useful again (after cracking once) that I can't figure out.

I can't figure out how to get back to the spike. I can crack twice at most. I think I'm doing what ex pat Brit was doing initially.

Infected Drops that can be "cured" by pushing a block ("pill"?) into them or running into them as a Gold Drop. Normal Drop + Infected Drop = Infected Drop. Gold Drop + Infected Drop = Normal Drop.
