I wanted to like this game because I like the basic concept, the TF genre, and seemingly having a lot of choices throughout a game is always nice. Unfortunately, there are a few problems that kept me from really loving this one.
The biggest problem is that the way the game handles choices, routes, and what content you see is often nonsensical. Far too many times I came upon content I was either forced into or out of for no reason I could discern... only to then look it up and find out that because I talked to character A instead of character B 20 choices ago I was forced into content X, even though it had nothing to do with character A or B. Basically, the logic behind what choice leads to what content is often obfuscated from the player. For some people this probably adds to replay value, for me, though, trying to figure out the correct sequence of choices to find the content I want is generally more frustrating than it is enjoyable.
Secondly, there's the sex scenes themselves. The leading issue with the scenes is that their quality is inconsistent -- some are short stories while others aren't much more than "and then you had sex." Further compounding on this problem is that the game itself often feels like little more than a series of disconnected sex scenes; rarely are sex scenes in service to any sort of story or specific character, instead a lot of them aren't much more than "then you went to a party, had sex with strangers, and came back to your room." Lastly, the game doesn't do much with the TF angle most of the time -- even in the beginning you go from being a newly transformed female into someone who'll willingly participate in gangbangs within about the span of ten minutes.
Finally, there's the images. It's your typical real porn stuff -- pretty much you either like the use of real porn or you don't. I do. My problem with this game's implementation of it is that there's not even an attempt at consistency in which porn stars represents the characters. At the start of the game you get to craft your character to an extent but rarely does it seem to effect which images you get. Rather than selecting a few porn stars to represent each body type the developer instead seems to largely just use whatever they have at hand when creating the scene.
Overall, if what you're looking for is just sex then you'll probably like this game. It has a ton of scenes and the writing is in actual English rather than having been machine translated or done by someone with a poor grasp of the language. If you're looking for anything else then you'll probably be disappointed. There's not much gameplay to speak of, there's no real story or fun characters to keep you interested, and even as a CYOA I wouldn't recommend it due to the amount of times I couldn't figure out why I couldn't take a certain action or why I was locked into a certain route.
