I like the concept of "magical girls with magical swords".
I'm not sure if what I hit was the intended end or not, but I killed a few enemies and made it to a kind of tower structure I couldn't figure out how to get over.
It's hard to say much about a prototype in this stage. I think the one possible issue is that as nice as the environment looks, it's really hard to tell what's actually walkable and what's just part of the background.
