is there a way I can save the progress i made when I leave the end the game? Even though I saved in the game, the progress still lost when I leave the game
This usually means the game hasn’t been properly extracted from the downloaded .zip file.
If you’re using Windows, right-click on the .zip file and choose a destination to extract the game files to, then run the unzipped Magical Viking Erika.exe from that location rather than from inside the zipped folder.
While this should allow new save files to be created and preserved between sessions, it won’t recover any save attempts from before the game was unzipped.
