public void Draw(Device device)
{
    // Render every block
    for each(Block b in blocks)
    {
        // It's possible the block may be null

Because the work for rendering the blocks is encapsulated in the Block class, it makes the rendering of the entire level extremely simple. You're still currently missing one important method that the other classes had, namely a way to update ...
