Not going to debate the value of the release or the time, since the vast majority here don't pay a single cent for the game at all. No reason to want to not support a dev if you're not supporting them in the first place, but...
I'd say that moving from an unknown sleep sex scene to one where the other person was ACTIVELY participating is a pretty big move forward, not back.
From you watching the game, sure it seems backward, but having her willingly (or at least awake) and doing a sexual act is pretty significant move forward to other things with her being involved and the MC not just being a sleazy sleeper creeper.
The argument that: "we don't pay, therefore we can't complain" beyond intellectually dishonest is lazy, and I won't retort. Devs can get feedback from here, many other media products do trials with public, audience testing and so on, if Devs are smart they can capitalize on that here. This is a forum, people can speak their minds, this tentative of a rhetorical-trap is pathetic, is just like the Woke mob does in social media to silence any criticism of their ideas, so please stop.
As I said before, I supported Serious Punch in the past, and won't do it anymore. But I don't put myself on a moral high-ground/pedestal above anyone on this site that want to complain about the game, and never paid a cent for it. On the contraire, please do so! We help people from supporting scammers like BoN, Icstor and many others.
About the scenes: MC got kicked out of the house because he was groping his mom, and she caved at one night of loneliness. I must remind you that in the first release after the revamp the mom (Kate) gives the MC a hand job, fully awake and willingly! That scene at the beach is so lame, and with no progress that could have happened in any prior release.
