The vibes are certainly good; the soft backgrounds are nice to look at and create a compelling atmosphere despite the prose being a little sparse with descriptions (though there is some nice imagery in the finale). I do think the banter gets a little tiresome, though, even if it's nice for the characters to have clear personalities.
The biggest structural flaw, I would say, is how blunt and frontloaded all the exposition is. The premise – a spirit haunting the protagonist – is pretty good, but how eager the game is to explain the history and the mechanics of this thing just saps out so much of the intrigue. Thankfully, the climax has some interesting beats that feel like good payoffs for some of the subtler setups.
