Yeah I gotta agree that this is basically just a collection of porn animations and nothing more (technically not, but it's so short and easy it might as well be). It annoys me when porn artists "make a game" but didn't actually want to make a game. Why make it at all? Just post your art on the internet man.
What's worse is, this is from the person who made Daisenka / Glory & Miserable Survivors, a porn game that was the opposite of this: underwhelming amount of porn content, but is very much an actual game. The underwhelming amount of porn content was very much a strong sour point of that game, but at least it was an actual game and I much preferred it to this one.
And they didn't even have to put that much effort to make this one good... just MAKE IT HARD!! Ofc longer is better but that takes many times more effort to make, so if you're understandably not willing to make it long at least make it fucking hard. Short & easy is barely a game. Please someone let me know if this game has a way to make it harder because I would actually really like the game if I could do that, even if it's a mod or something. The base gameplay is actually decently crafted and would actually be enjoyable if it wasn't piss easy.
