The demo doesn't really do this game justice.  The art and gameplay in the full version are really good.  It could use some sharpening, but based on other games in this space, there is a lot of potential here.  Dialogue is similarly good, not necessarily great - could use someone to sharpen a few grammar issues.  On par, though, this is a really solid game.  The issue is that it might be a dead game - a lot of chatter in the community that there hasn't been an update in about a year, and while the artist will occasionally post new images for new content, no real indication as to when it will be released.  So just know that you might be playing an unfinished project that will potentially never be finished.  (If you're the dev and reading this, I hope you keep going and get an update out soon).
