I absolutely adore the concept of this game! Reinventing narrative games in any way is so hard, so to see a completely new concept like this is super super refreshing.
Given the extreme emotional context of the premise, I did find it a bit odd that the protagonist was so ready to just completely swap out his emotional state. But I really applaud you for experimenting with something so new. It's a rare thing to see!
Also, the game looks absolutely stunning. You really nailed the vibe. : ) I had a blast playing.
