When you click "download" there's a link that says "no thanks, just take me to the downloads". That will take you back in to get the PDF.
It's a free game, the $10 is more of a tip (which I greatly appreciate!) Itch.io allows me to do a Pay What You Want system, so if you wish you can toss a few bucks my way but it's certainly not necessary.
