It was one of about a zillion free internet ultra-lite games from the period, with overlapping features. Find an archive of 90s-era internet RPGs (this was before PDFs, so they were all TXT files), and you'll see a lot of similarities. I don't remember most of their names, because it's been a long time and they're mostly forgettable.
Edit: Incidentally, if you like the game, that's fine. Enjoy it, and don't let me stop you. I never saw any value in the system, and was turned off by the tone, but that's my personal impression.
If you're interested in context, the 90s saw a huge profusion of game distributed via Usenet, FTP, or crude websites. Most were just ASCII text files, a few used basic html. There were some crunchy games, and a lot of AD&D derivatives, but the decade started with some high profile mainstream rules light games like Amber and Over the Edge, and they inspired a lot of people to try their hand at their own little games. There was a lot of discussion of minimalist approaches in the newsgroups. The Window was a late entrant.
