Giving a score to a demo seems ridiculous which is why I'm giving it 3 stars.. I guess what I'm trying to say is it looks good, but I need to see more before I could rate it officially.
Personally, I don't find the women very appealing, probably because I'm not a "breast" guy ... not that I don't like breasts, but all the women seem to have implants and/or born with Double D's... (Double d is the lowest cup size here), I personally don't find that creative and boring. I like variety.
As for the story, well this being a demo there's now ay to rate that. BUT, it does seem to be a generic story about some guy and his fam... with some weird occult stuff (Psycho seems to be into that kind of sh*t) I'm not saying this is a negative as even a simple formula like this can work very well if the game is good. In other words, the formula works, so don't try to reinvent it.
Lastly, and what I think is the most important part of my review is I really believe this is the future of VN's (or at least for the ones that aren't established yet). I think long gone are the days of VN's where the stills outnumber the animations. VN's will have to up their game with cutscenes, animations, voice overs original music, etc. etc. I think the demo is really showing what the future holds for VNs.
