Very good.

As there are many repeatable things, I guess you can simplify it by adding a function

AddBox := (map,box_color)=> {Scene.addBox({
size := e.geom._size;
pos := [3.25 + 1 + j * e.geom._size(0), 0.75 + 1 + i * e.geom._size(1)];
color := box_color;
drawBorder := true;
glued := true;
collideSet := 1;
body := 0;
layer := 1;
_slot := j + i * e.geom._slotY;
buttonDestroy := "w";
Scene.my.mapG = map ++ [pos]
})}

and use AddBox(Scene.my.mapG,[0.0, 0.3, 0, 1.0]) instead of this /\

I have a suggestion..... A much more intuitive method of making a new map would be for the user to add colored boxes to the new map as desired, and then when finished, click a button which will generate the text array of the new map (and will also create a new "memory card"). That way, a person doesn't have to keep track of each letter and it's corresponding position on the map.

Good job on the scene!
