Look at all that stolen art.
Even worse is that the sample pictures are nothing but examples of the stolen art. Those pictures are supposed to be screenshots of the game itself, interspersed with a few standalone pieces of artwork/3DCG, in order to give people a visual indication of what to expect from playing the game. It should show things like UI and dialogue and all noteworthy game features (one of which is the art, yes), not just pictures of the porn itself. When all you show is the art, and the art isn't even yours, you're showing literally nothing about what you put into the game itself.
Even in a game like this, which is your standard HTML game that's just a bunch of text with pictures in between, you should at least have a screenshot of that so people know what kind of game it is, as well as what the writing is like.
