Hey! I got to play the demo and I enjoyed it a lot!
First of all, the art, let it be the backgrounds, the sprites or the CGs, was absolutely beautiful! I particularly appreciated the expression work, both on sprites and CGs, it was excellent!
I also enjoyed Perrin a lot as a protagonist, and I LOVED how twisted their relationship with their brother is. I do love to see evil step-brothers, and welcome it as an interesting genderbent version of the evil step-sisters trope (which is even more interesting considering... well, Perrin).
I got interested in the politics of this story! Perrin's plan is a credible one to me, and it really contributed to grounding the story into something more tangible!
The mysterious Nuitépine, of course, is an interesting mystery I'm looking forward to explore! By the way, I love the name, it fits a dark forest very well (and the mention of thorns in the name suggests interesting things, whether about the dangers lying in this forest or about the more general motifs of the game).
It really was a great demo, and I'm looking forward to seeing more! Congrats on Sudachys!!
