My quick and rough review of it from Steam:

You play Reza, a young and naive amateur photographer caught up in the swells of the Iranian revolution guided by your house servant and friend Babak through the streets of Tehran as the undercurrent of dissent and dissatisfaction at the Shah and the ruling government threatens to boil over into chaos. Many different factions are represented here, and fairly as well, as Reza attempts to come to terms with the pressures of doing what is right by his friends, by his family, and by his country.

However, I am torn about the recommendation I am giving. I think this is an interesting concept and if you are at all inclined to games like Walking Dead or Life is Strange then I believe you will find something to enjoy here. Saying that, taken as a whole the game is rough and inconsistent.

The quality of writing and presentation are high, but at times disjointed. At one point you are given an interesting decision that I felt I had no basis to make. I was left wondering as to whether I had missed some key information or if the game was suggesting if I even had any right to make the choice. In either case the game did not surface its intent here well enough. The ending I received was incredibly unsatisfying. There are good endings and bad ones (in anything) but it was almost as if someone had left their work to the last minute, scratched some scribbles down and wandered off home for the day. It felt so completely unfinished.

The gameplay was muted, but that's fine. You take pictures at key points but you can't just take a picture of anything. You collect pieces of information that offer a background to the revolution and to Iranian society, although these snippets could easily have been copied and pasted from Wikipedia. Interaction with NPCs is limited, although the background chatter was quite good.

Technically the game was struggling to run at 60fps in crowded outdoor scenes on a 970, i5 3470 with 8 gigs of ram, so not well optimised. Movement felt jerky and Babak would sometimes block your movement. I get it, it's a low budget game but worth noting regardless.

My biggest concern, beyond the anemic ending, was how the game felt so curtailed in telling its own story. You meet a wide array of characters with different motives and expectations but you struggle to care for them, even about Reza, this character you gradually make your own over the course of the 2 to 3 hour initial playthrough. This is disconcerting since that initial playthrough expects you to make decisions that are most familiar to your own personality, whereas a second go at it will encourage you to pursue different choices in conversations, so I expect then to feel even more alienated by the main character.

1979 Revolution: Black Friday is a rough gem. It opens up a moment in history that you may know nothing about going in, and encourages the player to learn more about once the credits roll. But it is limited by a seeming lack of budget, some core issues with the way the story is presented, and an overreaching of what the team was perhaps capable of achieving. The art and music are brilliant and executed well, although performance was a bit of a let down.

Overall, if you can accept the stilted gameplay and the caveats expressed here, I think you will discover a game that you might never have thought you'd play, as well as a history you might never have thought you'd explore. And we should explore it, because the aftershocks of this time in this region still rumble low in the ground to this day.
