Thank you so much, its always great to have feedback, be it praise or criticism.

As for all the rest of youR points: please note that the 'Dev room' really is that, a development room. It's where I spend 90% of my time working in, its really a peak behind the systems and everything in it is merely a test. As this is the RED demo only Ruby was completed to a fully functional state while W,B,Y are only working at conceptual stage or even less (Yang can and walk and punch that's it).
Each Release will have me complete each girls moveset and balancing, for example in the latest unreleased build Weiss is fully functional and pretty fun i think. see below... tho even this is outdated now.
