I wish you could put some priority on improving sexual combat progression. As the others, I enjoy the game and appreciate the effort put into the custom illustrations, but every time I revisit it I quickly run out of steam and I have not even discovered all the possible scenes. I guess I'm looking for more game play progression to keep me going. While the extensive skill tree kinda suggests it at first, I quickly run out of reasons to choose new skills. I see no tactical reason to choose new ones as most of them seem to just be different in name not the effect in the given stance (I mean primarily the sex stances, as I prefer non violent solutions in this game).
Also the arousal vs lust mechanics is still a mystery to me, particularly as to which skill would affect which and by how much. To clarify all of this is a only an issue trying to win in combat as a top, which does not seem possible for all the monsters. For instance, from the recent patch notes I was expecting to be able to satisfy Harpy in combat by stuffing her ass, but after having her cum for about 10 times I had to give up. On the other hand defeating her with violence allows Hiro to satisfy her anally, a bit inconsistent if you ask me. On the other hand, tactical combat as a bottom is a no brainer, as most monsters already already want to fuck you anyway, so if they can be satisfied tactically it quickly becomes trivial and a bit boring.
I think what would help is more skill differentiation and skill interaction, not simple addition of more skills. To be fair, there is some interaction in the combat tree through stance changes, but in the sex combat it is lacking (in fact some very basic ones are missing, such as getting to a neutral stance from a controlling position in grapple, such as getting up from face sitting). I've heard term "emerging complexity" used in regards of successful gameplay systems. I am not 100% sure what it is but it seems to be lucking, as from my experience there is an initial complexity in learning the systen and then it becomes kinda flat.
At any rate love the game, just wish for more things to do in the future releases.
