Hey! I played the demo!
I think what really caught my eye first is the GUI! The transitions and animations between the menus were very great and polished!!!
The general direction was also extremely good: the art style is wonderful (especially the eyes!), the voice acting was STELLAR, the GUI looks amazing, the music tracks fitted the game perfectly and the backgrounds were carefully chosen and used cleverly!
The story was interesting! The love interests, despite all being yanderes, felt very different! I think Luke was my favourite because (he has a deep voice) he really looks reliable and straightforward, while still not putting the protag above everything (but he's a yandere so I know that ultimately he's still going to idolise her as much as Dane frtghtn).
I think Orli was my favourite character! I liked that she was competent without being overly-talented, I'm interested in exploring her past and the whole mystery about "the chosen one", the commission and what happens in Uldar is actually very engaging.
Good luck with the rest of the development!
