Revisited at 7.2b
The game is much better streamlined, the early story arc for Robin was re-written and is honestly much better. It's a great game, combining porn and really good story with cool twists. I can not wait for the next update!
As of 0.6.2
A very solid game with fun premise, intriguing story and cliche but very fun characters.
First off, don't get fooled by the version number, there is a lot of content and game in here. I didn't time it, but it's above 10 hours. Probably more.
Second, the style is not as serious as you might think at the start. Treat it like an anime story with all the tropes coming to play. Including characterization. I was a bit off putted at first (Robin's story arc is not the best executed thing in the world), but once Mia came to play, things clicked and I fell in love with the game. Don't expect King, expect Kishimoto.
The game encompasses many things - survival, fantasy, sex (lots of it) and menages to skirt the darkness, without submerging you in to it. The story has enough twists and turns to be engaging at all times. A few winks at the 4th wall here and there.
Also, animations. Don't be off put by the somewhat unconventional way the girls look, after an hour you won't care and my god is almost everything animated. Like almost everything has an animation.
Also, number 2. I've rarely seen RenPy utilized so well. The UI is not the clunky mess most RenPy games suffer from, the transitions are nice ans smooth and I've ran in to 0 bugs.
All in all, the attention to detail, the really fun story, likable characters and obvious improvement in the writing hooked me up and I strongly recommend the game to anyone.
PS: Don't bother playing on easy, normal is already quite easy.
