You're playing 2 characters, male and female, in a small city where these two take turns to interact with each other and their environment.
Apart from the interaction, you're presented with literally the same storytelling as in the previous game of this author, Good Girls Gone Bad: select your favourite partners and watch them develop their relations. If you don't want to see someone, you just ignore them.
This was a pretty straightforward 4- or 5-star concept, which made GGGB so appealing as well.
The main difference (apart from 2 chars) is that the character development mechanics has changed: instead of "kindness" vs "corruption" + "money", you're introduced with multiple stats: "Wits", "Charisma", "Athletics", "Lust" + "money" + "Willpower" + "NPC relations".
Not a bad concept if implemented properly, and it allows you to shape your protagonists accordingly. Unfortunately, it is not implemented properly, and the mechanics becomes a borderline between you and the desired content. Fortunately, there is an official option to "cheat" and play with max stats, except for "NPC relations".
So, why two stars?
It is primarily related to Female protagonist gameplay.
Story-wise, in 0.9 the Female is cut off her main sources of income by a powerful businessman, unless you allow him to fuck her.
The main problem here is that it happens "Deus ex machina", regardless you interacted with that businessman or not. (what if I told you that he is the Female's biological father but none knows about it in 0.9)
In other words, initially the game presented itself non-linear, and you developed your Female character in one of the multiple ways.
Later, its non-linearity is destroyed by this story "node" for the Female.
I'm pretty sure that in 1.0, players will get another "god of machine" and everything will turn out in one way or another for the Female.
However, the problem of gameplay unsatisfaction won't actually go away -- a player puts efforts which are crossed with the stroke of a pen.
Luckily, the Male doesn't have this story "node", which is nice but doesn't solve the plot problem.
Also, fortunately, the game still has a cheat mode, and you can technically (but not story-wise!) ignore the whole "Deus ex Machina".
P.S. Please don't get me wrong, the DeM is an absolutely fine concept in story telling, it just shouldn't overwrite all your previous time investment.
Here the businessman feels similar to aliens landing in the middle of the Female char development.
