I dunno, what happened
You have to get to the download through the link I posted,
http://gamemakergames.com/archive/clam-digger-2d
click the " Download Clam Digger 2d (EXE, ~5.34 MB "
if ya see the page that says
"Your download should begin within 5 seconds. If it doesn't, click here."
Click here quick and then quickly click downoad on the next page.
I had the timeout to download expire on me when I waited for the page to auto load stuff.
