In open worlds everybody can edit without getting permission or code!
Unlike the more common locked worlds players can't hold down the left mouse button and drag to create blocks. Instead, player must click to place each block one by one, This will prevent trolling.
Also, nobody can use god mode in open worlds. Only Staff can give god. However, whoever created the open world has no extra control over the world compared to any other player entering the open world.
Only basic blocks, metal blocks, gravity arrows, and the crown can be placed in open worlds. If the player has bought or received any other blocks that they would normally be usable in locked worlds, those blocks will temporarily be removed from the players' selection of blocks upon entering an open world.
There is no restrictions on smilies, chat, or any other feature besides the above mentioned limits in an open world. And world size is 200x200.
