So, after playing the last versions after the overhaul to completion, I waited a little to reflect on my experience and came to the conclusion that anything above a 1 star rating would be denial and/or straight out lying.
It seems really, really hard to mess up a game that has great art and clearly a talented coder so completely as this dev has managed.
For a visual novel, what this game is at its core, writing is obviously important. And this is where everything falls utterly apart. The writing is extremely drawn out and most of all, just very poorly done. Both the language used and the actual content is trash-tier. The game design is just as bad.
To top it off the game has a very appealing "cover" art (the picture used in the banner, and on the main menu), but does not deliver on what that picture implies - at all. At this point no one can definitely say if there will ever be actual porn in this game.
While this is not part of the actual game, and not part of this review, the development speed is extremely slow. That only adds to the frustration.
The poor concept and writing makes this terrible as a harry potter fanfiction, and an insult to everyone baited into actually playing it as an erotic game. Or just as a game, period.
EDIT: After a check-in on the current version, all of the above still applies. Well, we know now that there will probably be actual porn at some point, but what is currently included is more trolling the people who expected porn to come than actually delivering on that expectation. 1/10
