Hello! It’s possible to add Cinderella Phenomenon to Steam with your achievements and read text carried over. Only the save files will not be included automatically. Once you open the game on Steam, the Steam Achievements will be added to your profile. In case if the text you’ve already read could not be skipped with the Skip button, go to the Settings menu and under the Skip section, select All so that the game will skip all of the text Steam thinks you haven’t read with the Skip button. We hope this helps! Thank you and have a nice day!
