I really liked this. The music is quite beautiful and fits the tone of the game well, the art is gorgeous (the backgrounds remind me a little of Odin Sphere, which I haven't really played but was very impressed with the background art of when I saw it), and the writing is evocative and polished.
The starting point was a little confusing the first time. I didn't even know what Cassidy was exasperated by or tired with, when I was making the choice...
The choices in the demo didn't feel that significant (a lot of them being what Cassidy thinks while doing the same thing), the first time playing through, but I did notice one of the earlier choices actually removing an option from a later choice, so I'm guessing the full game may have more significant ones. I wouldn't really mind playing what amounts to a kinetic novel that's yuri and looks this pretty, either, though.
Either way, I'm excited to play the full game. I still have lots of questions, and the demo mostly just raised more.
P.S. The in-game link to this itch.io page during the demo ending doesn't work, sending you to "https//l2.itch.io/wv" (missing a colon). Also, I think "Elowen's" here should be "Cassidy's"? Still a stunning level of polish, though.
