I haven't gotten very far into this but there are a couple of critiques and might be worth an overhaul.
First of all, the story is very centered around potion -> corruption.
There appears to be nothing else to do than work->buy potion->corrupt->repeat. It get's monotonous quickly (which is why cheats exist no doubt). There's no socializing, no 'dimension' to the characters (and I'd WHOLLY recommend reading Sisterly Lust on that aspect). Making friends building a social circle, progression of 'skills' (see Summertime Saga) to boost 'earnings' over time, equally serve player enjoyment. Provide different ways to get income and different ways to spend income. I mean it's a lost opportunity you can't buy products in the shops from the get go. The different characters need stories themselves as a world that revolves solely around the MC is well...meh. The reason I say this, is because it should go hand in hand with the corruption and pacing.
Corruption seems to be one dimensional. While drugs are indeed a way to corrupt someone it's just one facet of an entire arsenal of defilement. Gently persuading someone that 'Yeah you're right, but this isn't soo bad is it?" is much more rewarding both for the player and the character. Another aspect is hypnotism and that's a fetish in and of itself.
Pacing is my next point. After you've done the work->buy potion->corrupt->repeat cycle a few times, there appears to be an exponential curve in there. It starts off slow building up bit by bit. I found it confusing as hell when I encountered the night time scene, that was much too early as far as I was concerned. Then it seemed to jump from "I feel a bit flushed" to "I wanna rape you" in three levels...and there are no other affects. It might be worth taking a few lessons from Spiral Clicker another game based on corruption (or rather mind control), it's a simple game but it paces nicely (or at least it did).
Then the English. Please. Someone. Make it stop. I kid, it's not that bad, but like most games where English is not the first language even with a translator, needs an English (native level) proof reader. There are some instance where it is jarringly unenjoyable to read.
That said mayhap what I have encountered so far is resolved later on (I'm not certain, but here's hoping!). It has promise and imo, worth following.
