Finding a secret will add one point, yes (and where it is possible to do two different things, you might get two points for one option and one point for another).

And a few more I've remembered that aren't necessary to win the game:

A particular failed attempt at opening the garage door.

Finding something hidden in the lobby.

Giving something particular to Samantha.

Giving something particular to Will.

At the beginning, depending on your answer to the question "What happened?", you will find an additional item displayed somewhere that will give you 1 point.
