Well the models are gorgeous, though I would hope for more variation in body-type among characters. Partly out of convenience, and partly out of preference, Devs all too often seem to make every female different in all ways except their measurements.
The writing quality is quite good. I do recall noticing at least one typo, but typos are easily rectified (It was said by Lore, before they entered, I believe).
The sex is very good, though that will not be the aspect that truly makes or breaks the game, in my estimation. There are dozens of great VNs here, with beautiful models having sex. Some even have solid enough writing. What really will matter here is the quality of the RPG aspects, both in terms of the quality of writing, and combat/general mechanics. I have no way to perceive those aspects, thus far. But if you nail that, this game will be in a class all by itself. If not, the game-play will just become an encumbrance to the porn that ultimately would have been been better off just being a VN.
The one change I would very much like to see is regarding the text-scrolling. Even at top setting, it is not instant. I find it a distraction that hinders my immersion, and I would much prefer to be able to remove it. Aside from that, all I can say is; I have been looking for a proper isometric, turn-based RPG, with sex, since the days of the original NES (though, admittedly, such would not have been very effective with 16-bit graphics), and this could be the best effort I have seen. But only if you actually put as much, or more, effort into the game-play, as you have done with the renders.
I shall observe your progress, with great interest.
