I just watched WHANG!'s video on the topic and something came to mind.
This might be a stretch but it's worth to try. Back in the day I ended up with a disc of goodies (one of those that used to come with tech and game magazines) and in it was the free version of the GameMaker engine. The engine was developed by "YoYoGames" and is now one of the most known game engines.
Back then you could go to the YoYoGames website and upload the games you made and download other people's games.
There were tons of games there from all styles, all downloadable and some even came with the .gmk files so you could edit the game yourself.
I remember seeing a lot of puzzle and platform games, but that place was wild and I do remember seeing some Harvest Moon type games there.
Some games there that were absolutely crazy, with violence and profanity, if the place was moderated it was pretty relaxed.
The old YoYo Games website seems like a perfect place for this game to have been, and it seems also very probable that it was made by someone in the community. The engine exported executables so you could redistribute them at will so it wasn't uncommon for people to redistribute them through their website.
I used the Wayback Machine before writing this post to see if there are "snapshots" of the website, and luckily there's a good sample. Obviously the games are not downloadable. I did some light searching and ended up finding games I played all those years back and loved, unfortunately, they are now lost too :c
The games used to be a single .exe file that you clicked in and it opened the game, it was very rare that the game came with an install wizard because it wasn't needed.
EDIT: The website still exists but it no longer lets you upload or download games from it.
Heres a link for and old snapshot of it on the Wayback Machine. https://web.archive.org/web/20090919172220/http://www.yoyogames.com/browse
I know this is isn't very tangible and is a more of a wild guess than anything, but I hope you guys find it useful for something.
Keep searching :)
