I have been making some progress in Seiklus, finding cool stuff, and generally having a good time. Then I check out the map(once I read the instructions to find the map button,) and find that there are a number of blinking lights on certain area blocks:

They alternate between white and black, and they seem to me to appear in a rather random fashion. Is this a sign of some secretes I'm totally missing, or something else I should be worried about?
