I think (hopefully) I've found the problem and have now added adarkroomfix.nex to the downloads - the previous version would autocheck for a save file, this version removes that - let me know if you have better luck
The game progression should be quite close to the web version, but the layout and controls are different (being keyboard based).
I'd happily take suggestions on how to improve it. So please send them my way.
Some design decisions came about from trying to fit it into the 48k version, but could be changed on the Next version.
The gameplay is quite simplified, lacking all those heart-warming phrases. I played both the web version and the Next version. In the Next version, the fire goes out too quickly. Meanwhile, other processes are noticeably slower; I was constantly fast-forwarded gameplay in emulator. There are also no hints about what you need to craft this or that item. They're sorely lacking; you have to play by feel.
