Man this game really needs a scene guide or a walkthrough.. Is there one??
No there is not such, afaik , mostly you get an Idea from the different paths and combinations, from this tread where different Players exchange their game expirence, or answer questions about the game, so I dare to asume if somebody, put himself trough the work of a walktrough it will be welcomed, I personally don't use any, because I like to experiment, and spam saving.
It has one of the highest replay values in my opinion.
