Your comment isn't correct, there is no sexual content in this game. Dubcon as explained by Wikipedia:
"Erotica or lemon fanfiction where the presence of sexual consent is unclear."
There's literally nothing of the sort in this game, you are spreading lies and saying horrible things to discredit this developer. I don't know if you're a troll or what, but it's not funny at all. I assume you are incorrectly defining the beginning sequence in which the MC is made to go to a different location for the first 15 minutes of the game, which has nothing to do with any sexual themes. There's no use for a content warning for something that does not exist, and the game script proves away what you're saying. The main character being made to go onto a ship is not dubcon. I would never enjoy games with any dubcon in them myself.
Edit: You must be a troll because you only made an account to comment this lie. I feel bad that the developer made a free game and these weird troll comments is the thanks she gets. Ungrateful scummy behavior.
