While preparing for our Steam release, we ported the game to Adobe Air to stop clearing your cookies, or using programs like ccleaner from erasing your save data.
Unfortunately, if you have an old save file, it will not work in new version because it is saved in a different location and a different way. We wanted to have a way to transfer the save data to the new version but we haven’t been able to get it to work.
We’re truly sorry for the inconvenience. Keep in mind, playing the Steam version of the game won’t overwrite your save data on the old version.
