I cross-checked it, the download link is working. It might be a problem of your internet browser, sometimes it hides the download popup. Just check the browser setting ones, if still didn't work then let me know.
I just tried again and the download button is there but when I click it it just sits there and doesn't start to begin the download. I tried the app again and it just sits in the download section and when I click it to start it just greys it out and nothing happens. (other games work fine) Sorry for the hassle!
