Uh, I might be wrong about this, but I think time in the game is slower than actual time. I just ran a digital stopwatch for about 16 minutes and a bit, and the game time says like 14 have passed.
Not going to call it one of the best games I've ever played, not by a longshot, but that's mostly because this isn't exactly my favourite genre. It was extremely useful to relax a little bit, and in something like 7 minutes, it gave me the sense of serenity that 5 hours of Stardew Valley would :3 Definitely a 5 out of 6.
I am sorry, but I believe the name "Long Live the Queen" is already in use 0_o It's even on Steam, so you might want to change the name a little bit at least.
