Well, il tell you, even if i dont know what the heck you want to know.
1:Addons. You download addons from the forums and go to Blockland folder and place them into the well, Addons folder. They add more exciment to the game. Like a M13 machine gun.
2.Single Player. Single player is where only you can build. You click B ( like in the tutoriual, sorry if i spelled that wrong) and select brick. Then with your bricks, or blocks, you can create almost anything you imagine.
3. Multiplayer. To do this, you need the full game. You can play with other people on servers.
Your welcome,
