I'm disappointed in this one, not because it's bad per se, but because I really think it could have been so much better.
Plot-wise it's fairly boiler-plate fantasy, but there's nothing wrong with that. The visuals are where it shines: there has clearly been a lot of effort and love put into it. Seriously, even the UI looks clean and polished, and that is something I really appreciate as a marker of quality. The music and the sound add to the atmosphere well too.
But the writing is weak. None of the characters or their voices are distinct, and for me the dialogue comes across cringy and forced. I find the inner thoughts of the character to be even worse and very juvenile. It's all modern in a way that doesn't fit the setting or characters, but more than that it's awkward.
As an example, here some of the first few lines of the game:
(Oh pew... T'was only a nightmare... Every night the same dream...)
Good morning sunshine, what is all the ruckus about?
Whhaa? Your Grace, what are you do-
Come on, chop-chop, don't miss our breakfast!
(I kind of vaguely question why the Queen would be waking the Prince if the servant is right there...? Or at all? Part of what I mean by being modern in a way that doesn't fit the setting, but that's mostly beside the point.)
My thoughts on this example:
It starts out with what I think is a typo - pew instead of phew? I'm not even sure. Then it jumps to ye old "T'was" before immediately abandoning it for modern speech and a sentence with a comma splice. I've seen far worse attempts, but in all honesty I tap out when I do. It's not a great start for either the grammar or its content.
Stylistically it overuses a few things -- ellipses can be seen in the example above. There is also a pattern of a lot of onomatopoeic words like "haha", but they are often stretched out or emphasized, as are some other words to show length. Like "MmmmmmmuuhhahaHAHAHAHA", real example. These are techniques that are meant to be used sparingly, and they aren't.
Most stories would drop the attempt to represent a sound, and instead describe it. It is the reason why we don't have all dialogue written phonetically to show accent, for example: because it is harder to read and quickly becomes annoying.
Here is another example:
"Eeeee... The tournament!!! How exciting!!! Hey, how did you get in here?"
First: whiplash on the last line, which should probably have been split into another (my opinion, anyway). But more importantly, the punctuation again, this time in exclamation points. You might (might!) see three exclamation points in a written work. But you'd never see it in two sentences next to each other like that. Also, question marks should likewise not be repeated, but if you must the pattern again tends to be in threes.
I would suggest picking up a book and comparing the structure of the dialogue. I think you will quickly spot a lot of ways in which the writing deviates from convention, and I don't think it's in a good way.
I hope I am not being nit-picky in an unwelcome way, because I really do mean this as genuine constructive criticism, and I really do hope it helps. Because there is potential here... but I think it needs a good editing. I hope you can get it to the point where the game does justice to your ideas - I do like them - but right now I don't think it's there.
