This was SUCH a good Demo!!
First of all, I wanted to mention, your art just keeps getting better and better; I really love the way you color hair and especially eyes, they look really expressive!!
As for the story itself, man, where do I even begin? The concept is already super interesting. I really like that Harper and Morgan are already married to begin with and that the main conflict stems from the fact that their relationship is not what it used to be and the gnawing suspicion that Morgan may not be the Morgan that Harper knows.
I love the way your writing always suggests things by showing the characters' actions or thoughts instead of them outright telling them. For instance, the way it's heavily implied that Harper is going through depression and grief with their dark thoughts, the pills and their mood swings.
Morgan feels like a big caretaker who has, understandably, started struggling himself after supporting someone with a serious mental illness. I honestly couldn't help but feel really sad for both of them. They love each other a lot but cracks have started to appear in their marriage: Morgan is a people pleaser who's reached a breaking point mentally and Harper is burnout and depressed.
The way you build suspense is also so good. I still can't tell yet if this "stranger" that the title of the game and the game itself keeps teasing is actually a supernatural entity or if he's still Morgan after his psyche has just made a turn for the worst.
I'm really, really curious to see how this will go; especially seeing how there will be 7 endings in the full release!!
As always, amazing story, Chatt, I'm looking forward to the full-release and more of your games!!
