As the MC is 18 at the start of the game then any flashbacks which appear to happen more than a year before the events in the story mean that the MC would have to be under 18, I believe someone on reddit has said that MC was 16 or maybe 17 at the time of sex scenes with Iris.
I pointed out that the MC in probably the best known AVN of them all also has a flashback scene that would have the MC underage unless the relationship was only very short, at most 4 months (which given the MC's reaction to not being in that relationship anymore is unlikely) because of the timeline in that game but that seems to get a pass.
Nyx is doing some Doctor Who shit when she says that "the author decides how time flows."
John and MC talk about the relationship with Iris lasting two years. Even if Iris and John leave for novascota the day before MC gets his tattoo, MC is still going to be 16 when he and Iris meet.
She doesn't explicitly state their age ever. And the models are not aged down. I might say "look, dude, your characters say this, and we're not morons" but the truth is, if the author says "they're of age" and there is no physical contradiction to that - it is no different than allowing Melody, and Dating My Daughter - LITERAL GROOMING SIMULATORS - because MrDots says "muh 12-year olds are 18" while including main characters in middle age. EDIT: actually, not just "no different" it is MUCH better from a moral standpoint.
Let's not pretend it's much different here though. MrDots is protected under the kink shaming rules, and I had a negative review of Melody deleted for mentioning other games... So I reposted it in the thread without comparing it negatively to other games, and it was deleted again.
It's really annoying because they are bad games with shitty renders.
