        let randX = Randomizer.nextInt(0, getWidth());
        let randY = Randomizer.nextInt(0, getHeight());
        if (i % 2 == 0) {
            createRect(randX, randY, WIDTH + i, HEIGHT + i, "black");
        }
    }
}

function createRect(x, y, width, height, color) {
    rect = new Rectangle(width, height);
    rect.setPosition(x, y);
    rect.setColor(color);
