I’m not the creator but people can give you tips…
- In you inventary you have a Journal (I dont remember the object name) so you know what have you done or forgot
- In the Slum there is a woman who can tell you (One time only) all the things you have left to do (More like she would tell you the adventures)
- Sleep, some mission doesnt advance if you dont sleep, also try looking for all the characters you know if they talk about somenthing
