Dev stated that in my previously listed guide there are missing scenes, but hasn't actually informed anyone of how many scenes are in the game or how to get to them. As I've used everything with everything, it's clear that the only way to access the missing content is to do very specific things in a very specific order and if you don't you have to restart your save file.
ALSO, for those of you that have been asking, yes you CAN start as a male character but progress is literally impossible without becoming a female character, as you MUST use the gene lab to open the scanner doors. The only scenes that are specific to the male character, are the venus scenes wherein your genitals are ripped off and the creature implants itself as your new womb, converting you into a Cuntboy. Many other scenes are simply inaccessible if you are male, such as the Harlequin and Brood Mother.
The idea of "small changes" and TFs is great, if there's any indicator or sign that it's happening, but as there are no stat bars for breast size or pregnancy it's impossible to tell anything is happening in most scenes if it's not a full transformation, and the full transformations which ARE significant are game overs or don't carry over (The Centaur TF or the Latex Bunny TF) unless you are talking about the gene lab. The gene lab TFs are barely noticeable if you started as a female character. Becoming Nila (I think that's her name) DOES make you look different in terms of your hair and eyes, the other one I didn't even REALISE my character had changed after doing it. I actually thought I had scanned myself into the system for security reasons and that was why I was now allowed to scan. As a MALE starting character, you do in fact transform gender which is noticeable, but, that's it then for the rest of your game file. You cannot become male again, and as being male only affects one scene and almost ALL scenes permanently change you into a woman, the actually "TF" focused aspect of the game is completely negligible. If the dev wants this to be a transformation based experience, there needs to be actual TF focused mechanics which actively affect gameplay or character design. Going from female to identical female is insubstantial compared to going from female to CENTAUR. But there's no focus on the significant changes, only... hair colour and slight shifts in breast size. Perhaps in future builds there will be full/partial TFs into different creatures, body horror, back-and-forth gender changing and more, because as the Dev stated, this is supposed to be a Transformation based experience, but this demo doesn't show that off. From this demo you would surmise that it's a pregnancy/horror based game which, when coupled with TF is a fantastic combo, but we'll have to wait a few updates to see that happen. For now, keep this on your watch lists and see where it goes, hopefully in the future we can get more clarity on what there is to discover.
