I agree with VocalRhapsody mostly. I liked what story I have experienced so far.
What's given has been good- up to the forest part and the festival of life, where continuation of the plot requires submission of the character to these things happening to him, and I much more liked the dream world tricking him into furthering the plight placed on him.
I'd love to be more drawn to the story, but at some point the player isn't guided through the offerings of the game and they're just sorta cut loose to wander about vaguely through the lore without any promise of story progression.
Also, the puzzles are really tough- and at some point you're more guided to them through curiosity of how the pieces interact vs a promise of exploring the plot.
Tldr: I like the plot, but based on how you referred to the game as Yuki Nuri's Nightmare(i don't remember the name) it might just be the sacrifice of choosing to make this style of game.
