Ok, looks like I finished all content in this version. Finally managed to get key from Sveta. What i did: I watched all her scenes; in toilet near pool, in dorm toilet after I gave her plunger and on sofa near TV. They all triggered at night, around 2 am. After that, I just continued to tutoring her and one day she asked me, what need to tell her roommate, I choose answer "for rituals" and she gave me the key after another tutoring session. What I found in the room did not please me, if you want to know what - read the spoiler.
I also managed to finish Evie quest. So here spoiler again
Also I improved her body, got cool abs on her stomach. I also noticed that when she workout she sweating in real time, it's really cool feature. Someone posted a screenshot here to show bug with clothes, but it also shows how you can improve her musculus. I'm not a big fan of muscular girls, of course it's nice to have such feature in game, but I hope we will not be forced to do so, with such quest where you need certain amount of strength, and we need to workout and as result her looks will change. I would like to see her close to original look, but with slight changes.
Anyway, despite little frustration I still like this game so far and hope to see future update here.
