From this demo it looks that game will be all right, there is no indication it will be great, but also will probably not be bad.
What I liked was attack changing depending on length it is used and general attack and life mechanics.
What I felt missing was story and boss destruction animation.
One thing I didn't like much was playing as some cartoon princess, not the style I enjoy.
After visiting your page I learned that all the possible main characters will be girls, it is not something I like, I will probably not be buying game due to this, why not make it 50/50? I see the developer team is all female with except of DynoStorm himself who probably does most of the work but why is his face covered? To give appearances of this being even more only female project? Sorry too much pretentious girl power for me, won't be supporting such project unless we get male playable characters too.
