Did not knew that one "The Sinful City Fight for Love" thanks. The other 2 are also 2 of my current 3. As for the third "True Husband , she is more like your stepdaughter but it counts. It has a good sense of corruption...I mean education.
The current version is 0.15.3 and is from 90 days ago as a free download on ITCH site. It only takes some time between developments. There are games that can take up to 6 months like Radiant but are worth the wait.
It is story driven and meant to immerse yourself and not just ctrl skip it. The innocent aspect of it just makes it feel more real and not blend. I for one will look forward the updates.
