First things first, the game is really great with a huge amount of potential, and I cannot overstate how much I like this devs approach. When it comes to specific stuff about the game I'd say:
The Plot: Yeah I know it's kind of surprising to talk about plot in a porn game, but it actually holds up quite well with a bunch of interesting lore that I'm guessing the dev will expand on at some point. The main story has a very basic but still original concept (there's only 1 game that I know of that is similar, and it goes in a very different direction), that is a breath of fresh air in a genre oversatured with the same stories. Also, how cool is it to be an actual dragon c'mon.
The Gameplay: While there isn't too much gameplay to be as it is a renpy game, there is satisfying sense of progression thanks to your stats and state of your allies. Also, there isn't any grinding which is delightful.
The Art: While there isn't much of it, it is of very high quality. The distinction between sex scene art and conversation art actually works in the games favour, as it looks good without a ridiculous amount of work.
The Writing: I think it accomplishes everything it needs to in a porn game. It's not only well written but also rather interesting with a ton of charm; you won't find the second coming of Shakespeare, but then who would want to in a game of this genre.
The Characters: While rather barebones in their interactions because of the early state of development, each character is clearly defined with their own quirks that make them unique. Most importantly they interact with eachother, with some pretty great scenes to boot.
The NSFW: Basically the combination of the above three, and I have to say the dev knocks it outta the park. Trust me that you will not be dissapointed.
The Modularity: Way too often games of this genre seem to be made to only appeal to the dev. But here, you can actually select which content you will and won't see in the game, which I have to say is a godsend as it gives you the option to customize the game to your exact liking. Also there's a bona fide power fantasy mode to select, which is always a great thing for experiencing all the content the game has to offer without grinding or making unsavoury choices.
The Developer: Love the guy, he seems to be very passionate about the project, and it certainly shows in the final product. From what I've seen he actually listens to people's suggestions and complaints, and doesn't think he's the greatest thing since sliced bread. Not to mention he has a decent work ethic and the game steadily progresses forward. If he keeps up, I think the finished game will be a truly great thing.
Overall: A 9/10 with an 11/10 for potential. Do yourself a favour and play it.
