I gave it a try and it is ok. I do have a few criticisms of the game though.
1) It would be nice if you could wander around some areas more and find someone to feed on when you need to. In my one play through I never did find anyone to feed on, other than the free starting one.
2) this one is in a spoiler tag because it talks directly about a scene in the game.
3) This kinda goes along with 1 above. But you can only go a few places and it is all about solving the investigation. I would like to have other places to explore, to explore the MC's vampire side a bit. Why not let each thing be explored just once and then you can do some other stuff that night. Then you sleep during the day and next night you can do one of the other story events. I think that would make the game more interesting. I know this is more of a visual novel but so is Fashion Business but it has things the MC can do outside the main story arc. I think that would help this game a lot.
All and all it is a decent game, what there is so far is solid but I think needs some polish and it needs to extra stuff to fill it out and make it feel more indepth. I mean I expected part of the game to be about exploring what it is like to be a vampire and we get none of that.
