Very coherent, self-consistent and extremely sexy game. What sets "The Headmaster" apart from a sea of similar games is that it actually feels like a complete game, an internally consistent experience and world that makes sense to you as you play, and enjoy the new roles it puts you in.
Other games often end up feeling like a bunch of oddball elements screwed on top of each other, but "The Headmaster" is, by contrast, made with a certain German quality and attention to detail, so it's a rock solid game experience that never does anything stupid to break your immersion in it.
I expected a lot of "otaku crap" to be forced down my throat based off the graphics, but there's actually no otaku crap at all in "The Headmaster". It is not Japanese-themed, at all. And that ends up being very refreshing in this game, because instead of the classic japanese spanking tropes ("Kyaaa it hurts, onii-chan!!11"), this game goes in a different direction altogether and feels more like a western sci-fi thriller. Again, there are no significant japanese elements in it, despite its looks the game's spirit ends up being very Western.
If you enjoy spanking, slow corruption and powerplay of any kind, this is the game for you. The way it's handled here is just delicious, and three heads above the basic spanking scenes you may have seen in other games. It's also absolutely chock full of sexy girls with unique personalities and fantastic posing work by the devs that gives them real life and cuteness.
An unexpected 10/10 experience that nobody should miss.
