A nice idea with a pretty presentation. While I don't personally think it fits within the limitation, this is less obvious than others to the point that it could be just interpretation. I can't go into too much detail because the game got locked every time when i was about to reach the area toward the south-west of the core, I don't know if it is an issue with reaching far, time or the way I built, as i noticed most of the time it happened I was trying to build far from the player.
