One of the games where the realism - or more accurately, the possibility that the methods preached by the MC it can actually be implemented with real results in real life - actually made the game so much more interesting that it should've been. There are some segments that in other games I would've skipped, but here I carefully examined them because I sincerely want to understand the mad but logical methods the MC employed to train his students. It also helps that he's both incredibly charismatic and confident in himself, a trait that every person would like to pretend they have and thus wouldn't mind their MC to have at all.
I give it a 4 star because I ran into a bug that was probably a year old, which seriously annoyed me. It the one where you're tasked to discover Amy's pleasure/humiliation/pain source, and the one where you're supposed to conduct a web search to find the porn magazine she mentioned just wouldn't trigger for me. As a result I was locked out of one of the most promising characters in the game unless I redo the game exactly the dev wanted so that the bug won't repeat itself, or unlock the gallery scenes to watch it, which completely misses the point of playing the game. And even then my save file is useless because it's bugged and, assuming this game reaches completion, I'll almost certainly be locked out of a true/harem ending or something. This is A YEAR OLD, it should've been fixed a long time ago.
Besides that, there are some continuity errors where certain events were implied to have happened, but not really I did them the other way around. I'd rather the dev impose a hard lock on certain content if that's the case, because it would be REALLY confusing when the rest of the cast gets their individual scenes.
All in all it's a great game, and despite how I made it sound halfway through the review there are barely any bugs at all, much less gamebreaking ones. But the dev definitely needs to pay attention to the continuity problem or similar bugs will definitely happen in the future.
