Hi, thanks for the comment. It'll probably be released on steam as a DLC but it's not decided yet.
And sorry that I'm not sure about the saving problem. It looks like the game itself works fine, and the save files should be in the "save folder"...
An update in that I finally got around to playing it again after the patch, and I can glady say that the game worked fine his time around. The issue last time may have been isues with extraction/storage on my computer, or perhaps otherwise a bug I encountered that the patch helped with. Either way, I played it now, and it was cute!
