Definitely one of the games of all time.
I bought it mainly to support the devs, now I just finished it and my feelings about it are kinda mixed.
I think that gameplay is close to tragic. Ofc, I get that it's supposed to feel boring and as real routine, but it's still a videogame, so gameplay should be at least a little bit fun.
Visuals of the game are definitely interesting. It looks very poorly done, but I kinda like it, it supports the atmosphere and makes the whole game feel more disturbing and uneasy to play.
And story is, unfortunately, dragged down by it's gameplay. While the core is very good, it just doesn't work very well (it's very unpolished and would definitely work better if the whole thing was a movie that could fully focus on it.)
Also, pacing is pretty weird, the first two thirds of the game are fine, but the final third drags a lot.
So, I'm really glad that I could experience this title and support the devs, but I didn't enjoy it as much as I would like to. It's at least very short, so it didn't feel like a waste of time.
