A nice fighting game with many features. If I had a comment for gameplay, is that I would have preferred the fighters to be a little faster. I would also have preferred the fighters to speak in another voice (higher pitched), even if it is not Japanese or English. It felt somewhat off; voice not fitting the face, I am not sure how else to describe it.
It crashed while playing, but didn't do something in particular; it happened when tried to jump (not sure if I was landed already or not), if that is helpful...
Generally, no idea where it refers to, watched more than half of the video the first time, I guess characters from an anime? Watched the credits, various names and stuff there. I didn't like the innuendo for those who do know what this is about (some other team characterized as traitors? I mean, what??)
Also, did I understand correctly that the keyboard controls are considered a "hack"? You may not assume that everyone has gamepads, or enjoys playing with one.
All in all, as a game, very cool with many prospects!
