Oh I also saw a forum thread about "is it a good playstyle given into The Last Birdling".
I think it was... Not very good (while the story was great don't get me wrong). There were obviously "good/bad", and the effect was especially showcased by visible "points" you'd gain if the interaction wasn't obvious (and they mostly were). Of course any player touched by the caracter would go for the "full good" combo as I did (well almost, I wasn't aware there wasn't more branching ending so I had the "thrill of choice" on my first run and made a few diverging stuff, but mostly, the mushiest ones of course).
I guess I'd prefered if there were "mom's point" too (so that there wouldn't be any wrong answer), and no "good/bad" obvious choices.
My RPG choices are best when they make me stop and wonder. "I love all the charas, but I have to wrong one... Shit. Shit shit shit what do I doooooo - goddamit".
