Well, well, it's a great update, the story is growing, the tension is also in the theme, the idea with two branches is intriguing. But as I feared, the building of relations with Mia depends on the chosen branch with Sarah, and this, as they say in my language, is "ni v kakie vorota", sorry. I highly disapprove of this design. Yes, I understand that the game is primarily about Sarah, and the all other girls are like additional characters. But it's extremely frustrating not to be able to go on a date with Mia just like that, but solely to annoy Sarah in order to advance the plot.
Mia's new model is not completely bad, I can play with her. No that world is stopped. Normal.
I join to the wish of the commentators above - to add the possibility of naming saved files in order to distinguish branches.
