Are you on PC? If so, you need to copy all of the files in your save folder and paste them into the new build's save folder.
Android build is a little less certain but I've been told the saves automatically carry over.
Yes, I am on PC. Thanks for the reply on how to transfer saves! I didn't even think about that. Thanks for the help!
Also, awesome game so far. Really enjoying the story and seeing where the passion/lust storylines will go. Also curious as to what new costumes Haru will get, as well as the purpose of the dress in the attic!
