I loved the demo. The art is great and the story engaging.
Well l'et's be honest the story is dark at the begining maybe more later.
I totaly didn't trust the first goddess even though I would at first chose this option. Let's bet on who is her agent on Earth, hum ?
I also understand how the MC is wary of this "bond", after such a first traumatizing event how can you trust someone and even more like that. I think the developing story can be really enjoyable on that part.
On the seven possible routes I'm soooo curious. My bet is either on the two gods or an harem and a no one route. (Please not the harem. I say this but it's my personal distate, I, of course, will follow the creator choice.)
I think you really have something. And you can create an amazing story. I can't wait to see what path you'll take !! (What it's usually the other way around ? Come on !)
