Haven't seen anyone suggesting it, and it's possibly for Category Extensions, but I believe it might be possible to do a Pacifist Any% run – as in, killing no enemies, stunning allowed when possible. Could be fun! :)

I can't find a good source on the release date of this website.

The earliest external resource referencing Sheppard Software is from November 23rd, 2005 ().

However, Google lists the website as being from May 28th, 2005 (). I've set this as the release date.

In case anyone can dig up anything else, please feel free to go ahead and update the information (or request an update).
