Just went through a bit of my backlog, so here are my two-hour-two-ending impressions for The Royal Trap: The Confines of the Crown. (I guess hidden-object games don't have a monopoly on colons.)
The story: You play Madeleine Valois, valette (a sort of caregiver and advisor) to Prince Oscar of Ocendawyr, charged to ensure he always puts his best foot forward, and to fulfill the political goals of your country by making sure he makes a good impression with a royal hottie to become a King. (They changed around the political and cultural sphere here, where the daughters are the heirs to the kingdom and the sons get married off to foreign countries to become kings, and the former princesses get the title of "Wisdom?" ...It was kind of confusing as to who was actually in power, but I just rolled with it.) But can you stand idly by and do your duty to get your close companion married, or do your feelings get in the way? ...Or maybe you can develop feelings for another? YOU decide!
The story is well-told and has some nice twists and turns. Having only seen two endings: the "happy" and then the "bad" end for one person, I can't claim to see all sides of the story yet - and indeed, you can't even see all the endings until you've completed the game at least once - but the makers of Long Live the Queen have a knack for spinning yarns full of political intrigue, and do their best to consider many possibilities, just as their characters might. Madeleine seems to do her best to weigh emotion against reason, making for a nice protagonist: conflicted, but level-headed.
The gameplay: It's a visual novel. (One with choices.) I'm not exactly sure to what degree every choice makes in the outcome - if it's a certain number of "good" choices or just specific key ones that matter - but it still makes you think diplomatically and at certain points choose sides, making you hope you can agree with one person without pissing off the other.
The graphics: For the most part good. The backgrounds are nice, and the characters mostly look well-drawn, although the page looks a bit crudely-drawn - almost a different art style - and the princess' brother looks downright off-putting but I'm not sure if that's intentional.
The audio: The music has some nice tracks. The "action/fight scene" one is particularly good. There aren't many sound effects, but I do like how they didn't reuse many, and even put in different "door knocking" ones. When the text says someone is knocking languidly, the audio reflects that.
The length: As I said, took me 2.8 (according to Steam) hours to complete one ending, then go back to the final decision and do the other one. Given 15 endings, and I presume some will be shorter than others, or you'll be doing a lot of skipping, expect some good replayability. I'd guess 12 hours to get all the endings if you're in a hurry. Possibly more. So, a decent length.
The verdict: I've played a few visual novels, even ones where you play a woman (Heileen 3,) and while they're not my favourite genre, I can say this is a good one. Of course, visual novels aren't for everyone. If you like visual novels, this one should be a no-brainer. If you don't and want to try them out, then you might as well go with one that has a well-thought-out plot, like this one. There is romance of course, but the political backdrop makes it seem more like "don't cause an international incident sim" than "dating sim," so keep that in mind.
