I spent a very good time playing this demo, so I'm gonna answer your questions!
Did you enjoy it?
Yes, a lot - I like the setting and the art/music. The characters are nice too! I can't wait for the full version to be released!
What was your favorite part?
The side-quest about Leslie's lost ribbon, I think. As silly as it may seem, it was quite endearing. And it really gives the "JRPG side-quest" vibes while playing a VN game!
How do you like the battle system? Were the right/wrong choices obvious, too subtle, or just right?
I like it very much! This is the first time I see that kind of battle system based purely on timed choices! The answers were right in my opinion, difficulty wise. They were not hard per se, but just right since this is chapter one!
Were there enough scenes? Did you find yourself with a lack of things to do? Were the scenes long enough?
Yeah! I don't think I even did all of the side scenes actually!
Did you enjoy the clothing options?
It is nice and pretty unique! I won't think of it as one of the main appeals of the game, but I still enjoy it.
There are moments where characters will comment on what you wear. Should I add more of this or did you have a lot of moments like that?
I didn't really have moments like that, but I like the idea.
Were the story/mandatory scenes paced well?
I think so, yeah.
Who is your favorite character?
Siegfried! But I also like Aldrich a lot, though I'd rather play as him so yeah, I must wait for the full release.
Who did you start to romance? Were the romantic scenes paced well considering this is only the first chapter?
I didn't start any romance - the character I was the nicest with was Fenris I think, but he isn't a romance option, so yeah...
Overall, I love this game, I love the battle system, I love the CGs and I like the sense of freedom it gives - VNs where you can actually wander around and do things at your own pace are an always welcomed rarity!
My only complaint is that I'm not very fond of Lilié, at least as MC (she's interesting, but I didn't like playing as her), so I was a little sad Aldrich wasn't playable in the demo. I don't like the romance options for Lilié either, since I wouldn't want to romance the other playable character, and I'm not into GxG. I really wish Siegfried and even more Fenris were options for her. If they were I'd actually play the full game at least once with Lilié, but as it is, I'll only play as Aldrich. This is why I haven't explored everything in this chapter yet - gonna save that for him!
By the way, do you have a release date planned?
