Well, just as I said during discussion with one of the game developers (one, that is to blame for awful story and writing) on one of the local forums, this is not game, or even visual novel, this is a very bad fanfic in HP universe.
About game - it has almost none game mechanics whatsoever, so you can't actually play it.
About VN - most VNs have limited amount of choices, with which you can tailor story to your liking, this piece of crap has only unbearable amount of text with little meaning behind it. And in native language, which is Russian, this is even more hideous. There are a lot of fanfics in HP universe with much better quality, if you are considering checking out this game because of that, just don't, go, google and read them, it will save you time and traffic (yes, they have porn in them).
Sad Crab team are one of the most stereotypical teams on patreon. They do almost nothing, post releases every half of the year, charge high and do not like any type of critics. Do not under any circumstances give them money or play their game (maybe only when it is finished, which, by the looks of it, will happen somewhen around 2050s).
Also, 404-get, it this a thing here?)
