WASD to move up arrow and down arrow to fly up and down left and right arrow seem like A and D but actually they help to view the block easily change focal length or objZ if its difficult to view the block change color to change color obviously change objX or objY if u wish to change shape of object
Completely by Miracle-Publishing :) Note: if u try to go inside cube and keep pressing W you would see something strange, you would suddenly another cube spawning but the controls have reversed; Its because you are on the other side of the cube, view is automatically reversed.
