"The file in the OP doesn't appear to work"
Haha, oops. Figures it would be the first post I screw up. The .swf was in a larger folder with some game files and I mistakenly thought it might be a stand-alone version but it probably needs those files to function. The entire game can be downloaded here:
There are a few more of Pubis' games if you click "Browse tehpwnzor's Shared Files" up and to the left of the download link.
If you've never seen it before it's definitely worth playing (IMO). Here's a preview pic, at a stage before the futa. The game's in Moonspeak but easy enough to figure out.
