Good points. No, the game is not fully finished. Of course you can reveal all the endings, but there was still another update planned (which is supposed to finish the gallery and other adjustments). However, the dev doesn't have time for that because he is mainly busy with the main game.
Do you think there's not enough horror in it? The game is mostly about dark humor and a lot of the bad endings are horror-themed. And true ending is pure horror.
So no new content, just finishing up the gallerie?

It's sad, but at least the game is finished. As for the rest... Yes, I noticed an abundance of dark humor, it even amused me, especially on the third date. And about the secret “true” ending... It was all a dog’s dream, but I didn’t understand who the conversation was with when they shot the dude, and how did this help advance her release? I played the original and completed both modes that are currently available, but I don’t remember anything like it. In addition, the original looked like a joke and not horror, and the ending of this game is truly horror, or at least creepy. Well, then the VR headset flies off of us and we look like we are some kind of... half-dead in the morgue overgrown with purple vines, which held the VR helmet... What? Just like a dog's dream. I prefer to think that our guy stayed on the island with the girls, even if that's not true. Although, knowing the genre of the game, most likely the secret ending is true.
And I didn’t understand the joke with the crystals. I collected everything, a woman dressed as a plague doctor came to me, said that the crystals were not mine and took them away. What was this for...
