Getting the most out of it
To lay a block down, aim at a face of an existing block and press R (or right click). The new block lands on the face you are looking at — it will not go where you are standing.
Flying is on by default — double-tap Space, or just walk off and land to switch back.
The filled box tool builds a wall or a floor in two clicks. Hollow box gives you a room.
Replace swaps every block of one kind inside a box — good for re-skinning something you already built.
Worlds save only what you changed, so exporting one and sending it to someone else is a small file.
