Finally, I managed to do it.
I had given up on the cross and passed onto the pillar swastika. Then I thought of were I might go wrong.
I was drawing like I did the first pentagram in the temple (not the blue one), meaning i wasn't letting go of the mouse when drawing, even if, I should have, since the cross needed two lines. I did that, and it worked!

Great and , Sunlight.

Do the drawing fast, cover the whole square and most often- with no breaks in the lines (as you did).
