FDM finally did the trick for me. There is a problem at that end, though. It got to 99%, then sat with no progress ("0 B") for about 10 minutes (with occasional jumps to impossible speeds that lead me to think it retried the download with the completed part coming from a local cache of some sort).
I have to play with a quality of 3 to prevent lag on my system, which keeps me from appreciating that fine detail in the texturing, I'm, sure. My problem is a general one: I don't much get into this genre. I like the humor and the themes, but as soon as I get stuck on something, I tend to quit, and never go back. It does look like a very fine point-and-clicker, though.
