... Can we get a downloadable .swf file for the flash version? Flash isn't limited to web browsers, it's a gaming platform and .swf files can be played in the official platform, Adobe Flash Player, which is still very much attainable (new versions aren't created, but the old versions exist and can be used to play Flash games much like someone can still play N64 games on an Nintendo 64 platform).
Update: An official download URL would be preferred, but I believe I've found it through another website that hosted the Shockwave Flash (.swf) version of your video game's demo. Here it is if anyone wants to download a copy of the demo (playable on the Shockwave platform - Adobe Shockwave Player): https://www.kongregate.com/flash/konduit_5e36cc9bd7533572759e07372fed1b04.swf
