I finished the ""trial"". I liked it very much, it has a kind of slow start, but that was good to build up the situation and get the player more invested in the characters. It has a lot of "mystery" scenes, where the protagonist (or other characters) does not know for sure what is happening. I think it could use some more build up in some scenes, but I think that it was already enough for the kind of game it is. Also, this "trial" took me more or less three to four hours to finish, I felt that it was, at least, half of the game. If this was less than half of the game, I am very excited for all the content that it will have. It also good that it has both CG scenes and sprite animation.
I went in the trial with some good expectations, but even so, it was better than I expected. If anyone is interested in this game, I recommend the trial, it already has a good part of the game, with a lot of scenes. The author was generous with the content given for free. The only issue I had is that the recollection room did not work for me, so I recommend saving before H-scenes if you want to rewatch them later.
