This game is already really big and has A LOT of lewd content, my guess is that it won't be long before the game is one of the largest/lewdest adult games out there.
I'm personally not a fan to spoil the story/stories too much or hold the player's hand through everything.
We've recently changed the intro of the game to show what's to be somewhat expected. Aside from a very accurate game description on the web pages the game is downloaded from, there are 2 warnings and a quick guide in-game that explain what's going on and what's going to happen to some degree.
If by that point people still judge this game too quickly it's more on them than it's on us.
