I appreciate constructive criticism, don't worry about it!
Yes, Aspasia is a major character who will only get more major as she figures into some later plot. She will def have her own ending. I love writing her!
The elemental separations are based heavily on real-world alchemy, particularly the classical elements. Similarly, a lot of the aether/nether stuff is heavily inspired by kabbalism. You're absolutely right that they don't all split up evenly (more mobiles than immobiles, etc), but I wanted to respect and research the originals as much as possible, even if it didn't lead to super clean classifications here.
I've gotten a lot of feedback about characters not interacting as much together, and I'm working to alleviate that! Sam/Metatron got a LOT more interaction last patch, Sarah and Celica have a bunch upcoming, and as you get a bit further into most of the character trust scenes (especially Ashley) you will see more interaction. I will confess, this is my first game, and still a work in progress - I've kinda just been trying things to see what works - it's definitely not finished or perfectly polished! But there will be more interaction for sure.
That Sarah CG was actually the first thing I ever commissioned, on a very low budget, and we had some miscommunications. It will be redone properly at some point in the future.
I actually like the Deepwoods background! But a lot of them could be improved, yeah. Commissioning backgrounds is just expensive af and I haven't done it much, so it'll be a learning experience too.
Thanks for your thoughts, and I hope your holidays are going good!
