(Just to recap, with help from CTRL+C and V) If you had enough blocks you could stack them and build a tower on them. And enemy monsters will attack the bottom but the blocks increase give the tower bonus fortification and health. The higher the blocks the more range,fortification,and health the tower has.
(related to the on-going comments of stacking blocks) If you had enough blocks you could stack them and build a tower on them. And enemy monsters will attack the bottom but the blocks increase give the tower bonus fortification and health. + if you agree.
@wry0 It doesn't make real sense to move upgrading buildings because imagine that doing it in actual. Can't really move something that's upgrading huh?
