This is an unusual game/VN, and on different fronts. The first one is the 3D art, that I've seen only in previous projects of the same dev. I felt it was somewhat weird at the beginning, but it has grown on me, TBH, and now I really like it. At least it is pretty different from the usual roast of Daz3D and HS based 3D art we find here, which tends to make all games similar (from a character POV, of course).
There are other unusual choices, such as the UI, with text on a vertical box across the left of the screen. And, then, the big one: the game is to be replayed several times, as much as the ones necessary to achieve the different endings (don't worry, for each time, it is possible to avoid repeating the same scenes already played).
The core of the game is, again, the harem trope, but one that is very well implemented: the MC must remember how, during a period of one month that he spent on the hospital, he went from timid guy with no girlfriend to a guy with several women on his harem.
Although incomplete, the game already has many hours of play and includes some things that are (unfortunately) rarities but contribute for a well-rounded experience: many spoken dialogs for the girls (that have pretty sexy voices!) , good ambiente music and sound effects.
I'm looking forward to find out how this one ends. Hope the dev can lead this game up until completion.
