Okay, I did it! Played this one too!
It's not really a setting I like, so expectedly I have less affinity for this game than your other titles, not to mention I hate stat raising (I won't be skipping that, obviously, since I want the most out of my endings haha!). But it was still a nice experience - I was really worried, to be honest, but I still liked it.
Same goes for the art - not my jam, but still nice enough. Well, that's not entirely true - I love the art for the CGs, but the sprites are not my jam. From an objective point of view it's gorgeous though.
I'm not gonna lie, it'll probably remain my least favorite of your games, and I'm way more excited for "Deep in the Forest", as stated on that game's page, but still!
Paul is nice enough as a protagonist, though I feel his exact personality will depend of the stats, so he's more of a blank canvas (how appropriate!) than your other MCs. I like Gilles a lot though, and Émile is interesting too. Ferdinand and Bertrand didn't attract me, but I'll see in the full game.
All in all, I'm still eager to play the full version (or future demos, if you're planning on uploading more).
I did notice a small bug... I think? When Ophelia was on the scene, and moving around, her sprite wasn't moving smoothly all the time, but jerking around a couple of times.
Also, not really a bug, but more often than not, when the music track changes, it seems very loud at the beginning, which is a bit weird. I think it's because most of the tracks begin in an abrupt way or something? It actually made me jump once or twice.
