This is a beefy demo well worth your time.
Getting to customize the MC is nice because you actually get to see her a lot, which is also good! She's been thrust into the role she's always wanted but wasn't sure she would get, which is a neat place to pick up her life. She needs allies but the choices you have to make don't always make that easy. That being said, the politics aren't so bad that you feel you have no good options.
The resource management system isn't too difficult, and having to spend resources in order to choose certain options is engaging. The phases you can enter (such as when you read and decide on petitions) are welcome asides that expand on the view of the kingdom.
The art is lovely and the facial expressions are fun! (The MC biting her lower lip is probably my favorite.) The characters are all very much their own people and make you want to interact with them. The love interests are interesting enough that I'll have to try them all, but the Master of Murmurs is just too hawt.
I'm glad I backed the Kickstarter and anticipate spending a lot of time with the full VN when it's released!
