I don't think it was this game, this one was released first in 2018, maybe I released a demo in 2014 or 15 or so (it took 4 years to complete), so if you're talking around that time then maybe you played it, but it was never a flash game.
I found it.
Vosmug 2015 - Demo Version v.0.1.1
You are correct, it is not Flash. I had been downloading various flash games when I originally downloaded it, some of which were converted into exe files. (I wish a lot more Flash games did this. Yes, I know it limited them to Windows… but now that Flash is dead, so are a ton of flash games that were never ported to console… now trapped as swf files that even flash emultators don't correctly run… I miss the flash games that never made it into the massive archive of flash games that were lucky enough to be preserved…)
Since GHV - demo 0.1.1.exe was barried in the depths of my flash folder (animations, games, music videos…), I must have mistaken it for a converted flash game.
What engine or code was it built in so I can put it in its correct place?
On a side note, I have no idea where I got the demo. Maybe Newgrounds, if you ever uploaded it there…
In any case, I'm glad it was finally released; even if I missed the début.
It's made in Game Maker, I always posted it in my own blog and I guess someone reuploaded it somewhere else.
If you have SWF files, you can download the desktop Flash Player Projector:
https://www.adobe.com/support/flashplayer/debug_downloads.html
Then drag the files into it or set it to launch the projector when double clicking SWF files.
I was not aware adobe still offered flash support at all.
There is one that the standalone player won't work for, that I know of. It's kske or something like that. It's just a K-On paper doll game, but downloading the swf never worked, there was something on the site that made it work… some form of DRM I'm sure.
Regardless, thank you; I will try to check the link when I have sufficient PC access again.
