you should put all the map files into a zip. would be much more convenient to download.
They are in a .zip file. I suspect that you are logged into your google account, in that case you can see into this zip file. It's a "convinient" google way ... On the right top corner, close to your google avatar you should have an arrow pointing down into short line. It downloads zip file. I cannot wait for a constructive critique of the map.
