This game belongs to these fighting games where what the keys and combos do is almost completely arbitrary, you have to study the movesets and play a lot to get good so I won't even try. I don't really care about them gameplay wise. To me, it doesn't really matter.
I'm talking of them as characters. Not fighters. If you look at the character selection, half of them look very similar and they pretty much feel the same once you see them in action.
In fighters, diversity is key: Big guys, small guys, big girls, small girls, weird guys, etc... I get that, if we are only gonna get lolis, the diversity is inherently hurt. However, I think one could do better than this, be a little more creative.
The little princess, the tomboy,... we have how many mages now?
I'm just talking, the game is incredibly niche, he can do whatever he wants with it and it won't change how unique it is. Just sharing.
