The game is INCREDIBLE. I have to say, the devs must live in NYC because they have the environment of the subway totally accurate. It add to the realistic horror element for me as a resident.
The only thing I would say is, it is not 100% clear and obvious what you need to do next often. Some items are hard to spot, and other times, you won't exactly be sure what the devs want you to do (like opening the train door scene).
Overall, I would back them on Patreon just to get this full game expedited. I need to know what else waits in store!
