This is not something you would expect from a porn game. At least i didn't. Yeah, there are some spicy CG and animations, but it wasn't something worth grinding the "three in line" sections. Unless you are really into lizards, that is.
The beauty of this game is within it's dialog and story. It is super silly and funny, contains a lot of references and quotes from slavic culture and memes. One problem with this is if you are not very familiar with the source of all these references and quotes you will most likely consider most of the text and lore random and/ or chaotic. I am slavic and i still didn't understand half of the jokes.
The "game" itself is "three in line" kind of game in which you have to move pieces in order to create chains of stuff to get points and unlock scenes.
Most of the game juice is locked behind playing those three in line sections. The game will throw some kind of objective in order to unlock certain root that leads to scenes. So if you don't like that kind of game than this one is not worth it.
In conclusion: If you are into lizards, you are confident in your knowledge of slavic meme culture and you don't mind playing "three in line", then this game is worth playing to the end.
Otherwise - get a gallery unlock or something.
