Intriguing enough story, cinematic, dramatic, and the world-building is superb, but there's not enough done with it.
There's not much in the way of gameplay really but as someone who enjoyed compelling stories like Everybody's Gone to the Rapture, etc., I don't much mind that.
My main problem with the game is that some of the scenes seem deliberately dragged out to increase the play duration on an otherwise very short game. How many time do we need to see Karra throw up blood on the train really?
Other than that, there are too many characters we know nothing at all about, and the game asks you to answer questions we cannot draw on knowledge to answer, which completely undermines the point of the game. I also feel sometimes that the conversations don't feel natural.
Excellent world, intriguing, but ultimately not enough. Either wait for a sale or watch a video.
