So I've searched through this thread and I have seen 1) some hate regarding the type of game this is and 2) several requests for a walkthrough (including from myself).
Having played through about 5 hours of this game I think I can shed some light on both of these.
#1 This is an incompleted corruption trainer game made in RenPy with CG 3D model assets. There doesn't seem to be any animations but there are plenty of pictures that fade into one another to kind of simulate movement. Overall it's not a bad effect.
Technically, there are 3 different routes you can take: Love, corruption and nightmare. From what I hear, the love route is a dead end and never finished and this is an abandoned game so I wouldn't expect any updates. The corruption and nightmare routes seem to have plenty of content though. I played through the corruption route so far and will update this post as I get more info.
Why is this game controversial: the "nightmare" route looks pretty dark keeping the girl in a cage and such, and the "corruption" route is pretty dark too honestly. At best, you could say the protagonist "Biist" is a sociopathic control freak and sexual predator. The girl is 18 years and looks 18. Which to an old fuck like me, looks pretty damn young. The "corruption" in this game is basically an attempt at slowly breaking down this girl's will and pseudo or outright blackmailing her and she is NOT happy about it. The "nightmare" route looks even more coercive, maybe outright rapey.
Now I'm not judging, just want you to know what you're getting into.
The other problem with this game is the "grinding". Much of the "work" done in this game is repeating similar events 2-4 times each at a certain period of the day. The fact that the events are often done at the same time every day means you have to click through a bunch of menus waiting or doing busy work to get to to the next correct time period. Repeating events with only slightly varied scenes or a couple of lines of extra dialog is confusing and boring. Am I supposed to do this scene 3 times, or is this game broken?
Finally, some people object to the physical appearance of Biist. Biist is a monster of a person on the inside, and he is ugly crippled on the outside. If you're not into that, you probably won't like this game.
All that said, this game is actually pretty good. The grinding sucks, but even with the grinding this is one of the few games I've downloaded lately that's kept my interest.
The girl is beautifully rendered, gorgeous and not a generic bimbo with anti-gravity boobs. She looks like a hot young college student.
The story is, I think, fun if you are into pretty dark humiliation and corruption. The most similar game I have played to this one would be the excellent and highly recommended game "Cohabitation." For me personally, this game really pushes the limit of being too dark, and too grindy. But if you're into humiliation/male dom and willing to accept that this is a fantasy/hyperbole story I think its fun and the scenes are clever and well done. Even though I feel like a rat pulling a lever for cocaine, I kind of like the slow-burn and that the game makes you work for each scene. You sort of get drawn into Biist's evil but patient plot to enslave this girl.
The background scenes are a little plain, but to be honest I'm glad that the developed spent his time and energy on the girl because she comes across in amazing detail and with a lot of personality.
#2 Walkthrough.
Corruption Route:
You don't really need a walkthrough because of the "hints" system. This pretty much tells you what to do, however there are a few things that can be said.
There are 3 stats: Money, Strength and Corruption. However, the 3 stats are basically irrelevant once you figure out the correct routine.
Money is made by hitting the "work" button at your computer for $5 an hour. Do this anytime except between 10am and 2pm that you have nothing else to do.
Strength is gained by going up and down the stairs between 10am and 2pm when Rachel is in school. Do this everyday betwen 10am and 2pm unless you have another task to do.
Corruption is gained in 1 of 3 ways, either you help her with her homework in the kitchen (she feels like she owes you a favor) or you insult her and make her feel stupid while shes working at your computer (she feels like she needs your tutoring). The latter method will make Rachel mad at you. This lasts for one day, and when Rachel is mad you can't interact with her at dinner or the kitchen table or most other places. You can also buy corruption (5 points) by buying condoms. This is pretty much unnecessary.
The Corruption Route has a "Main Quest" and "Sidequests". You can access "hints" on both Quests, which are actually pretty explicit instructions on what to do next, from your computer in your office. The Main Quest Hints are doled out one at a time, depending on what you need to do next. The Side Quest Hints are given as a series of 15 instructions.
1) Talk to Rachel in Kitchen at 9pm
2) Check her at night to see if shes wearing panties (go to her room at midnight)
3) Talk to her again in Kitchen (narrator will tell you she needs to become dependant on you)
4) Talk to her again in Kitchen and tell her not to wear panties
5) Check her at night to see if listened to you (go to her room at midnight)
6) buy sleeping pill and give it to her when she's studying at 6pm
7) Visit her room at midnight and molest her
8) Buy a webcam and see her masterbate under her covers (couldn't get this to work)
9) Hide her duvet at 11pm
9.5) optional (watch her masterbate without her covers)
11) repeat watching porn at midnight to get a handjob
12) buy a dildo, hide the dildo in her room at 11pm
13) watch her at midnight on cam using dildo
14) repeat watching porn at midnight to get a BJ
15) watch her at midnight on cam and pay her a visit
I don't have all of the Main Quests written down because it took me hours to get through them all and they were all pretty self explanatory. One area where I was confused though, you need to spank Rachel a few times to get her to dance nude for you. She will refuse the first few times.
Hope this is helpful to you all.
