It sounds like he specifically created it to share their experience with rioting and (maybe) process it in their own way, or at least that was the catalyst. I think the main difference between this and other games which "gamify" real life things (so, CoD, Battlefield, Papers Please, Democracy, Civ, literally hundreds more) is how personal it is to you, because to me it has the same potential and approach as many of those other games and some of them deal with (to me) heavier, much more political issues.
I'm not saying the game is for sure innocent, no political game ever completely avoids being one sided and sensitively covers all the information and emotional weight of their topic, but I'm saying as someone who has been in a few protests (not riots, though) that this game doesn't strike me as egregious compared to any other of those games, just going off the store page.
Honestly I find the CoD games more offensive politically, and I still occasionally play those. They are absurdly heavy handed and don't deal with nuance in the slightest, and belittle a lot of serious problems with our world and struggles.
