Although it is told in the rules that review should be about the game and not about the developer, this game suffers hardly from its developer that it would be misleading to not to also talk about him.
The game, when it first came out, was revolutionary. It delivered what many people were searching for that time: 3D visuals, good graphics, good story, cute girls and quality sex scenes and VR support. Still to this day the graphics, nice 3D visuals, VR support and cute girls still stay the same yet the development of the game has now came to an undesirable state.
The developer tries to milk the game's supporters to such an extent the charm of the game is now gone, with nearly-yearly updates and not delivering on what the audience actually wants, the sex scenes. I am not saying developing the story of the game is a bad thing, but most people play the game for its lewd content and story shouldn't be its main focus, rather what holds those sexy times together. This also hurt many fans with the 2nd 4th day update, which only brought insane lore dump and confusing development without any sex scenes.
Still disregarding the developer's poor practices, the game still has its unique soul; with cute girls, quality sex scenes and somewhat interesting story.
If you want to experience this game, play it once or twice thoroughly and then be done with it. If you try to follow its development and wait for the next update, you will be quite frustrated.
