At first, the art caught my eyes, it looks very elegant and unique compares to other games recently so I decided to try the demo out and I'm glad I did.
Everything looks great (the art, the GUI, etc) and the music is very pleasant. I like that we gotta choose the character's background, and the approval system, reminds me of Dragon Age series. The idea of having someone soul in mine is also a plus, it's like having a bestie you know, to gossip and have girls's talks about guys, Lionel is not an option since he's also a LI, sorry mate. XD There's not much I can say about the story or the heroine since this demo is too short but the writing seems decent to me. I hope she's a smart and funny person, in other words, has personality, 'cause there's nothing more frustrating than playing an MC that's nothing more than a pretty doll.
Overall, I love it so far, looking forward to the extended demo with all the LIs. :) I tried my best to express my opinions in words, hope I didn't fuck up my English too much, it's not my first language. XD
