SpinMag game

I used the same rotating magnet from last week and added a different scoring mechanic. I also added a levels using png images to place items on the map. There are four levels, but the game is really tough. Currently it only has one life. I wanted to add more, but ran out of time. I again spent a bunch of time reading about texturing and lighting and have not made the progress I had hoped. I'm considering a game that uses spot lights as a mechanic next week.

This is a screen shot of the game.

This is the map image. Each pixel represents the location of one of the 3d spheres.

Here is the code that reads the map image and converts it to 3d objects.

protected void LoadMap(String mapname)
{
    // the map is just an image file with pixels of various colors
    // red = barrier
    // black = open space
    // cyan = closed space
    // green = starting point
    Texture2D map1 = content.Load<Texture2D>(mapname);

    mapwid = map1.Width;
    maphei = map1.Height;
    int numpix = mapwid*maphei;

    if ((map == null)  (map.Length < numpix))
    {
        map = new byte[numpix];
    }

    // want this map to fit over the circle, so calculate the size of each ball
    // scale of the ball
    mapballsz = (int)(maxballdist*2) / mapwid;
    mapxstart = -(mapwid / 2-1) * mapballsz;
    mapystart = -(maphei / 2-1) * mapballsz;

    /*

     * ms-help://MS.VSCC.v90/MS.VSIPCC.v90/MS.XNAGS30.1033/XNA/GetData``1_B8CC1053     */

    Rectangle sourceRectangle = new Rectangle(0, 0, mapwid, maphei);

    Color[] retrievedColor = new Color[numpix];


    map1.GetData<Color>(
        0,
        sourceRectangle,
        retrievedColor,
        0,
        numpix);

    goalcount = 0;
    int i;
    for (i = 0; i < numpix; i++)
    {
        if (retrievedColor[i] == Color.Cyan)
        {
            map[i] = MAP_CLOSED;
        }
        else if (retrievedColor[i] == Color.Red)
        {
            map[i] = MAP_BAR;
        }
        else if (retrievedColor[i] == Color.Blue)
        {
            map[i] = MAP_GOAL;
            goalcount++;
        }
        else
        {
            map[i] = MAP_OPEN;
        }
    }
}
