I...honestly kind of agree with you.
I think the game is absolutely beautiful and clearly a lot of love has been put into it, but I feel like the quality of the writing dipped a bit after the demo. The demo pacing is also a lot slower compared to the main game, and I didn't enjoy Anton's route half as much as I did Emile's route (especially where you don't call out Denham.)
Lillian immediately getting in with Anton also just...confuses me. XD
