Well, that's an interesting game in the making!
I just did my first run of the demo - Nottingham route, and I can only say I'm hooked.
The character art should not be my style, but somehow it works and I really like it, and I love the backgrounds. Music choices are very nice too. One of the most notable qualities, aesthetically speaking, is the GUI though. A good UI adds a lot to the general ambience of a game, and it's important not to neglect it. And well, it IS gorgeous.
It was clever to skip the prologue in the demo - not only it leaves a bit of mystery about the general situation, but it also allows the players to check out the meat of the story without being too lost or getting heavily spoiled. It has also a very decent lenght for a demo, honestly! Especially considering it has two routes.
Also, it's always a pleasure when you can encounter sudden (and narrated) game overs even so early on! I'm a sucker for that!
I can't say anything about the Sherwood route for now, obviously (I'll comment later about it - probably tomorrow since I'm not going to play it now), but I'll share my thoughts about the Nottingham one.
Well, what can I say - you used one of my favorite tropes in fiction, so it was hard to resist. That trope being a protagonist that escapes (or at least loathes) an arranged marriage and then still finds themself "stuck" with said fiancé/e and ends up falling genuinely in love with them. Not only that, but I always wished for a Robin Hood inspired game that would allow the player to romance the Sheriff. The fact it's both at the same time (and that the trope is about the right character) is almost uncanny, but it makes me so happy. Though, because of that, it IS likely I'll only ever play Geoffrey's route - at least on the Nottingham path - I may still play the Sherwood one for Will, as I love the character in the legend, and he seems to be my type in your game too. It's not much of an issue though - I regularly play romance game and only do one of the routes.
That being said, I liked most characters that appeared on this path (not a huge fan of Gui so far). Marion herself is charming and witty, Alanna is fascinating (even if I'm not interested in romancing female characters), Meissa is an unexpected cutie and well Geoffrey himself is everything I love and more.
The world seems interesting too, and I'm eager to learn more about it. Though, again, I have that uncanny thought that our minds are connected, because of Nibiru and the cat-like features of it's inhabitants, considering in one of my own works I have a cat character whose name is Nibiru.
I don't think I can say much more, so far - and it was already long! Not to mention I'll be back for the other path.
