click to place a cell and click 1 to switch to a moving cell(you will be selecting 1 when you start) click 2 too select rotater cell last click 3 to switch to duplicator. Oops forgot too say that to start click space and to change dirictions on a cell is to hover your curser over a cell and clicking space(doesn't work with duplicator)
I'm sorry I couldn't add deleting just click the green flag again I had to rush becuase I haven't posted in a long time(I have been learning Unity(a Game Engine)) -Happygames42
