There is no direct relationship between the levels of tiles created versus how many times you can click to zoom in. It all depends on how big your viewer is and how big your image is. If you want to be able to zoom further into your image, perhaps you need a bigger image. You can also use the maxZoomPixelRatio option when creating the viewer to allow zooming further (though the image will get blurry when you zoom past full resolution); for instance, try maxZoomPixelRatio: 2 (the default is 1.1).
