That goblin can indeed if you don't have walls surrounding the WHOLE base.

Yes. Even if you put walls on the border, the border is actually 2 squares deep, so there is a one square spawn space on the border guaranteed.

Yes, a unit can attack from any side.

yes. best not have those sort of bases.

That should be said in the loggin tips... Instead of "you can gem up the barbarian king once th7"
