The idea is good overall but I like more when there is focus on visuals. For example, when you write "*blushes*" line you can use sprite with blushing character and sorta. And I want to say that composer really did a good work making vibe for the story thought I think music in the end should be more menacing.
Btw there are characters without sprites and idk if it's bug or you couldn't make it in time.
