@keibin - try to use the settle button after you make the castle so that it doesn't lag so much in the beginning. You also might want to try to save/export the text and line up some of the elements in a text editor.
The elements are represented as such:
","biv,1040,420,1,1,0
Where the first "biv" is the element, the second is the x coordinate, then the "y" coordinate then the thickness, then height then angle.
This is the base code for the Matrix

The first part of the equation is basically the background stuff then the elements (starting with "c":[ and the last part is the terrain [0,0,50 ...] 230 is high and -20 is low. On the screen editor you cannot make anything smaller than 0.5 wide (which is 10 pixels or 3 high {which is 300 pixels) but outside the box as it were, you can do whatever you want!
For an exercise on terrain, open up the editor and save the blank screen. Copy the save/export stuff and change the terrain from [0,0,0 ...] to 230,0,230,0 and so forth... Add some kings on the pinnacles and you have this:
{"l":["tg","mg","bg","wc","id"],"r":["rw","rwc","rs","rsc","ri","ric","rb","rbc","rfb","rpb","rrb","rf","rl","rr","ra","rp"],"c":["king,135,380,1,1,0","king,225,385,1,1,0","king,315,385,1,1,0"],"n":"","t":[230,0,230,0,230,0,230,0,230,0,230,0,230,0,230,0,230,0,230,0,230,0,230,0,230,0,230,0,230,0,230,0,230,0,230,0,230,0,230,0,230,0,230,0,230,0,230,0,230,0],"o":-1,"":""}
Hit the settle button and it is hilarious!!
Enjoy!
