Blockland Main Adventure Mode is unlocked when you click on the golden brick that Badspot programmed into the map called "Slate" that is a default map that comes with Blockland. This Brick can be found by loading Ice Palace, going to it, then going left along the edge until you reach a corner. Then if you plant 666 64x cubes that are aligned with the corner and go strait up, when you reach the top, you will find a 1x1 plate that has an event set that gives you further instructions as to the coordinates of the golden brick. By the way, what part are you guys on?
