Very interesting setting, characters and the story looks very promising!
Do you think you'll stick to your home made skill system or will you implement everything in the narrat default one?
I loved the character portraits as well :)
Right now I'm not sure, not really because of the skill check system itself but more where I think the game might be going. I've got ideas for other parts of this that wouldn't be pure narrative that Narrat wouldn't be able to handle, along with a bunch of other ideas that are out of the scope of what I can do (music, primarily) and would need to see if others would be interested in working on it. That's along with those ideas needing a bunch of testing and beta players to see if they're actually good or not.
Basically, this project would be beyond the resources I have on my own to bring it to a level I'm happy with. Or more I do have, but I'd be spending the next few years on it alone when I want to be messing around with other stuff right now.
All this to say: dunno.
