I am stuck early on it says to check on sister but every time i do she just says she slept okay and it never progresses.
Did you played one of the current available versions, right? 0.9.1 fixed some bugs of stepsis on 0.9.0. Then I think there are some problems with files conflict, cos it happens with some people and other not.
Have you played previous versions of the game before? If so, could you please delete the older files or temporary files and let me know if it works then?
