There are some punctuation mistakes (there's no comma before that or what) and articles missing, but I've seen worse in some paperbacks.
The main problem I had was how mean Natasha becomes, in spite of you making the nice choice, as with the drunk. Sticking a drunk with a pin is not funny. Drunks are sad people. That's just sheer meanness.
It's too bad. I was starting to really enjoy the game up to then. After that I couldn't care less if Natasha got her passport and I was hoping that someone would kick her. I didn't bother to waste my time on the rest of the game.
I was about to give the game four stars before that. Now it's barely two.
