I don't believe it's fair to account for the amount of time a game took to develop when rating the finished product. I also believe that this game could have been much more, but I'm reviewing what we have when we got it.
If you've played Vampire Notes or the dev's earlier stuff you'd have very well known what they tend to focus on. Presentation, exceptional artwork, weak gameplay and weak corruption. This game falls into the same holes and has the same strengths.
RPGM games tend to be pretty ass in terms of gameplay but a lot of that comes from seeing the exact same format iterated upon a million times. You find AOE spell, spam it. This game does nothing to improve upon the base systems other than giving it a snazzy UI, and admittedly that's a flaw in this day and age. I can appreciate the puzzle sections but the core fights need to have at least something going on. See "Revived Exorcist Priestess (tentative)" or "Wolf of Shadow" for a fresh take on RPGM combat.
The H-content is lacking in terms of variety, and potentially amount, ymmv. Croix is extremely hot yeah, but how many of the scenes are just the same frame of her getting her tits grabbed? Yes it's an extremely well drawn cut in, but it doesn't substitute for full CGs.
The writing has pros and cons. I played this with MTOOL before dazedanon posted the AI version but I got the gist. The plot is somewhat basic, the characters are better. Quirky sure, but interesting.
Where this game shines is in the presentation, maps, and art. The transitions are a nice touch, the UI feels unique and doesn't hurt my eyes, the maps are most certainly not just stock assets or your boring rural RPGM town. You can tell that this is where the majority of the development went, and you either appreciate it or hate it for that. The actual character art and CGs are something else though. There's a legitimate argument to be made for the art being best in class, shame there isn't all that much. What we do get though is fantastic.
So all in all, it's not the best game, but it's a very pretty story. The art's damn good and with any porn game I consider that to be the most important factor. I'm biased, four stars.
