The gameplay is very simple and that's how it should be, not to get in the way of the (touching & terrifying) story.
So congrats, good game and very good idea to talk about this subject this way.
I read on some comments advising to do localisation, I think the first thing (and easiest) would be to just add english subtitles when Abdullah talks. I'm not an english speaker myself and sometimes had some trouble understanding.
Good luck with the game ! (and the rest)
