Incredibly disappointing. GHV and XT are actively my go-to nowadays for porn games. I literally can't be bothered to look in the direction of a porn game if it doesn't have these mechanics and am tired of keyboard warriors (see above my comment here) telling us to suck it up and stop complaining when these kinda games are fucking dead/dying. Kincaid? no more grabs for years now. Crisis Point Extinction? no more grabs. Future Fragments and PASEC are the only one of note that've been made in a long time, meanwhile 9 million visual novels or similar types are released every single day for people to eat up like slop.
Calling people "keyboard warriors" for defending a developer making a game they enjoy themselves is a weird stance to take.
Developers will either make things that earn money or make things that they themselves enjoy, hopefully a combination of both. If you feel that your favorite genre is drying up, you can help out by purchasing games from your favorite genre (remember, itch.io allows you to pay more than what the game actually costs! So you can entice your favorite developer to make more of a certain genre by giving them more money!). Or, you can contribute directly yourself by becoming a developer yourself.
My favorite genre is the same as yours, though I still found this game good enough to be enjoyable and I am looking forward to Vosmug's next game. Though with that being said, I really would also wish the next game was an action game with a female protagonist.
