This is an excellent game, and has easily become one of my favourite VN's that I've ever played. Perverteer is probably the best at writing hot – but believable – talk during sex. And also one of the best at doing buildup and hinting at future exciting sexual scenarios. No one else does setup and payoff with as much mastery, and is as consistent at never drifting into cockblock/frustration territory while doing it, as the dev/writer for TFTUV.
As for the overall VN, it tells an interesting and compelling story (with obvious influences from Mass Effect, Dune, and other space-based sci-fi, plus a unique mix of fantasy elements that I hope might be a hint at a future sword, sorcery, and sex type VN from this dev). The code/paths are well tested and straightforward to play, and I didn't run into any bugs apart from some annoying variable setting regarding achievements (not a problem unless you played early versions like I did, and tried to use those original saves). The music is top tier, and perfectly conveys intimacy during sex scenes, tension during action scenes, or a sense of the unknown as the reader is introduced to alien worlds and races. Characterization is well done, and each individual has a unique personality, with believable interactions, conflicts, and growth over the course of the story. The pacing is damn near perfect, and even though the dev can write some great prose, conversations never feel long-winded like in too many other VN's I've played. Also, kudos to the dev for giving the player a couple of interesting and non-rival (!) male friends to pal around with on the journey, which is a breath of fresh air to see in an adult VN.
There is really good use of kinks throughout the game as well (scenes with domination and watersports content are two that really stood out for me) to add extra spice to many of the encounters. The one problem I am finding in general with the game is that there are perhaps too many love interests, which can feel at times like it takes away from focusing on the much more compelling core characters. However, that isn't a big enough issue to not give this a five star rating, and recommend it without reservation to others to play.
