This game is a rough draft of something that could be amazing. It starts out great and goes downhill after a few episodes.
It's worth checking out for the good parts, but overall it's poor as an adult game, which is what I think it wants to be reviewed as. As a porn game, it's a bit low on scenes and variety but ok. If you're looking for a game where crazy stuff happens, then it's excellent.
Good art and dialogue, creative ideas (for example, the acting scenes), some great characters ... brought down by too many over-the-top dramatic twists. There is a genre shift, but the bigger problem is that most of the premise only makes sense as a porn game (ie, ignore things that don't make sense), but later on the game wants to be taken seriously as an adult game, despite having a foundation with too many holes in it.
Anyway, play it until it jumps the shark. If that doesn't happen for you, enjoy! If it does, unfortunately it's not going to get better.
