The game is finished - so the only thing we can do now is to report the bugs we encountered. I doubt that the author wants to change the game code and add new scenes or people.
I too am missing a few things.
It would be nice to introduce a new character in order not to forever do the same with the others, e.g. aunt <- enough to add her at the end of the game - and possibly throw her in there some side mission lush, warp mind, command mind - places pool in the evening, bathroom in the afternoon, laundry at night, etc. :)
Alex's friend could also be developed in the end she sleeps with her younger sister - it would be nice to enter at night when we take the sleeping bag and tap both two on the bed.
