That is YOUR way to see "Innocence", not the dev's.
He designed an innocence meter for that purpose : measure MC's Innocence.
Watch carefully when the game make MC's Innocence decrease...
It is when, through the players choices, MC decides on her own will to act naughtily instead of staying a good girl.
That is the essence of the choices of this game :
choose for MC between staying a good girl or act naughtily... Read again OP post description by the dev, it is clear the game works that way I am saying to you.
I do not say your way of seeing Innocence is bad,
I am just saying that you are no more legitimate (me either) about that matter than the dev in HIS game HE designed.
With that, you can understand the event with the ugly guy in massage center is NOT a loss of innocence, because MC did not act naughtily on her own, she was harrassed by the ugly guy.
I checked : MC did not lose innocence is that event with the ugly guy : 100% accurate.
The reason the dev to put this event may be to show us and MC the city is dangerous and full of bad guys. The dev also gave a name to this ugly guy, that means for me, like in any classic RPG, this guy is meant to be seen again.
Rather than "insert self sim", I see the dev to have his own style which is expected to not have a plain and boring game...
And other good games down here also have their own style.
As players, we are not legit to question such design choices only the dev can make... A game to not follow your way or meet your expectations does not mean it is bad or poorly made about choices.
The only right we, as players, have, is to decide if we like those choices or not...
I tried Bright Past, AWAM and GGGB a year ago...
- For what I remember (my memory is bad when I did not like what I played ^^!), Bright Past did not fulfilled my expectations about relevant choices : I mean I remember to have had the feeling I could not figure out the routes from the choices... I played not long, maybe 30 minutes of content before deleting and conclude : not for me.
- I have the same concern as many players here about AWAM : it lacks substancial progress in storyline and the character I had the most expectation in was Ellie but she did not have enough content and her route was not clear enough to be seen as promising by me: again, same conclusion... not for me.
- GGGB : I may be the only one but I see the drawing to be ugly (I do not like such comics-like visuals) and I did not like the flow of the game : again I remember to have had the feeling to not being able to choose easily between options on screen to figure out the route I may prefer.
I do not see where those games are doing better than this one with the choices put to player, I do not remember being impressed by their relevance (and how they shape the story) . Maybe my memory does not recall enough of them.
