This is an early days game and I am really liking the premise! I have only played one other Pyograra game and that is soldiers life can tell this will be in the same vein. I do have a criticism though and it more around taste more than the design of the game I think. I think the game actually makes Cassandra be too much of push over too quickly or at least through the blackmail scenes it seems very one-sided.
It is a given she has a head start and therefore you have to grind through her card onslaught but maybe because of the lack of content right now (which i can totally understand) there is little to show of her taking initiative or even blackmailing the protag. I like these kind of games more when the one you are trying to dominate fights back, perhaps that is why I like BF games so much, part of the thrill is overcoming an equal challenge. It is even alluded that Cassandra is used to being 'top' or enjoys controlling (even though her innate sub nature maybe becoming exposed) I just wondered if more stuff like that may be added? Mechanics where Cassandra attempts to wrestle initiative away in the sex scenes or do blackmailing of her own to try to present a greater challenge to the player or even cause a bad end if not careful. I recall soldier's life having something similar and that made the game a lot more compelling for me where the wrestling for who 'lead' was a common theme.
Anyway it is food for thought, if is not Dev's cup of tea or not anyone elses I can totally get that. The game still looks to be fun all the same.
