Of the last update, the line with the most significance for Luna's future is, I think, when she think while masturbating that she doesn't care if people know her secret. At the verry least it's the story thread I look the most forward to following as it would bring a lot of changes to the status quo. Sure for now it's a thought she only got in a moment of euphoria, but it is still a thought she had and one she could think about more before making a decision about coming out. It's simply the first step in that process and it makes me hopeful that this process won't drag on for ever and that if someone finds out and tries to blackmail Luna it could backfire in the blackmailer's face. 
Speaking of blackmail, I have a few theories about Isaac and funnily enough they aren't necessarily mutually exclusive. The first is that he is being blackmailed in crossdressing himself and is not cosplaying of his own free will. (Even when taking a stroll in the city.) An other is that he might be a dickgirl himself (or herself) wearing a chest compressing band during the day. Thinking about it what looks more like a kid than an other kid. his parents seeing a little something between his legs when he was born could have assumed he was a boy until puberty hit and then tried to hide it by not letting express his developing femineity. (That brings up a lot of question about baby Luna and how her parents knew she was a dickgirl and not a boy. Is there other markers identifying her as one at birth? wouldn't it have been easier to hide her as a boy until puberty? But that's for an other time. It's Lewtopia's story to tell)
About the cucking of the father. It could simply be his own kink or he could suffer from impotence for whatever reason and want his daughter to be his surrogate. Only time will tell.
That is all my thoughts about the game for now. G2G.
I so want to Netori Risa away from her douche boyfriend.
