One of the devs here =). Glad you enjoyed the game, despite this very annoying problem, which we will definitely look into! Did you play a downloaded version or the web version?
Also yes indeed, she might not be quite as smart as she thinks she is ;).

Min is definitely not as smart as she thinks - but then, neither am I, it seems. The problem is identified and should be fixed now, thanks to the sharpness of esdoubleuk. It was a recently added autosave feature not playing nice with everything else in the browser version.
I'm very sorry that you lost your progress, it sounds like you got your teeth into the game nicely. Thank you for your kind words, despite the frustration.
Do I understand correctly that you did finish the game, but are not sure if there were different endings possible? I can confirm that there's just the one ending - there's only one way Min's story could end up XD
Yes, I did finish the game, and quite enjoyed it-although I did restart a few times when I realized I missed something. The annoying thing was that I wanted to check if anything changed if I hadn't gotten the "sense of foreboding" effect, since it seemed to foreshadow the ending. The annoying bit is that I couldn't go back and retry since I was unable to access any of the save files. I'm glad you were able to fix it up.
