Wow...ok, where to begin. This might sound a bit harsh.
We'll start with the bad :
First, I have to ask, why the hell is a game that's supposed to be based in London (we'll ignore the license plates) filled with such annoying Engrish? Cmon man, get a proofreader. I mean, I've seen worse, but the game is based in, you know, England.
Second, fuck me, this shit is convoluted as hell and the in-game "walkthrough" and "hints" aren't even worthy of being called guidelines. They're cliff notes of the guidelines that refer to the actual hints or walkthrough.
Third, for the love of God, stop gating content behind other content (goes for every dev to be honest). I don't give a fuck about the maid and her saggy African village feeders, but as far as I can tell I HAVE to interact with her to unlock other shit. I understand story progression might demand certain things but I'm fairly sure paying Abi $100 to dunk her tits into the dishwater isn't a crucial plot point. Same with Alex the school slut.
Fourth, wow, the MC is a completely irredeemable piece of shit so far. I don't want to come across as a white knight, and I understand the game is called Total Corruption, but maybe insert a few more non-douchebag options for those of us that don't plan to take a shit on our sister's face in the future (and Jesus Christ that look on Himiko's face was heartbreaking for us non-sadists). May want to add a humiliation tag, slave tag, and a blackmail tag now, and probably others later on.
Fifth, I know it's not that far into production, but there's fuck all to do for most of the days right now, and I can see a shitload of grinding for bullshit (gotta get muscles up to 20 so you can lose another swimming contest!) in the future.
Now the good :
First, the renders aren't bad. Nikki, Kathy, Jinny, and especially Himiko and Nicol are very pretty models (eye of the beholder, yeah, I know).
Second, and I know I sort of listed this as a negative earlier, but that blowjob scene with Himiko captured her despair pretty well. It's not my thing, at all, but I can appreciate the fact that it was well done for those who are into it.
Third, the game has a fair bit of promise if some of the glaring issues can be addressed, especially since it's already been out for like 8 months. That said the amount of content isn't exactly overwhelming yet, so who knows.
