I'll begin by stating my criticisms with the game:
The TG aspect of the game seems pointless. I'm neither for or against TG content appearing in games, but here it seemingly serves no purpose and I can see it as a mild disturbance to those who don't care for it while not offering much value for those enthused by the tag.
I played the free version of the game, which includes only one save slot. Day one works perfectly with this, but day two features at least one circumstance I've come across where the absence of regular saves may fuck the player over a bit, as it did me.
The game somewhat lacks the inconsequential. On one hand, all the characters that are in the game serve a meaningful purpose. But because everyone has a purpose, there's not really any smaller details or characters that exist primarily for flavor. The game's atmosphere and writing is very good, but a few more interactions and characters that didn't directly tie into the main plot would liven things up a little bit, and important characters could do with a few more options of interaction without direct consequence.
Bad ends and sexual interactions could do with a little more variation and as above, could serve to be available in less "meaningful" ways. What is present is good, but once one finds oneself in a sex scene or bad end, the structure of what is happening is just a linear path until the end in most cases. A few bad ends could do with more "oh, maybe I can still escape" moments, and with a lot of sex scenes consisting of multiple acts in sequence, they could do with at least minor breaks inbetween in which the character can react and evaluate before suffering the next obscenity. There could also stand to be more options for minor perversions unattached to the primary cast.
It isn't finished.(At time of writing) You'll reach a point where you will be wanting more and it won't be ready yet.
Those are my criticisms. Beyond those, I'll just refer to the score I'm giving the game. Honestly I just want more. That's really the only thing wrong with it. What is present is all very good, so I just want more of everything.
Maybe play it now? Maybe wait until there is more to the game? It will likely become a better experience the longer you wait, but if you play it now you will still certainly enjoy what you get.
