I ventured into this game without prior knowledge of RWBY (although I did know of show's existence it newer stood out to me and I knew pretty much nothing), thinking yea this game looks cool and having finished the current update (at the time) I had to watch RWBY to compare it to the game. Gotta say you did a pretty good job from characters to writing probably better than the show itself, even though it is not really too hard to do better than the show from 3rd season onward but still. Here are some key points which were better.
1. The importance and meaning of being one's partner (You did this even better than Monty, God rest his soul).
Once I started watching the show I was kinda feeling meh when I realized that it did not play an important role at all. Yea we do see it a little at the beginning with Ruby and Weiss and Jaune and Pyrrha, but beside that nothing really special.
2. You did well with the main crew too except Penny (Love her here and in the show, she is pretty much my fav, but she shouldn't be the part of main cast here). Again this might be because I played the game first, but Ruby and the gang do not feel like the main characters at all. Dunno if it's just me, but Jaune felt like the main character from the start (had the best development too).
3. Ozpin and the orphans. Nothing special to say except that is awesome as fuck and I am surprised that in RWBY he does not have a secret unit at all. A unit he personally trained to be the best fighting machines and with unwavering loyalty would make things much easier for him, but if at this point he has one it would be bullshit.
4. The Main character David di Kabegis. Mysterious past, a maniacal semblance becoming of the MC, and most importantly going from weak to strong. He is potentially the only character who could do ''magic without maiden powers'' by having a fuck ton of semblances and I simply love that idea. I believe that he (at full potential) and Jack could go 1v1 against Salem and give her a run for her money (While we do know shit about how strong Salem is compared to others that feels just right). RWBY at this point really needs a truly op character like him on the good side.
5. And last but certainly not least Jacqueline B. Ivory, pretty much the best character in the game. I was like watching the show hoping she would show up at some point, but nope, I mean the show did not end so who knows hahahha. She is an OP character done right. Dunno if there is a semblance stronger than hers that feels completely fair to others. If she was in the show by the end of Volume 7 I think she would be able to trash the whole team RWBY alone and other maidens 1v1 easily, and I would not even be mad about it. Actually, it would be therapeutic to have someone defeat Cinder that does not have special powers.
So in conclusion, congrats on making a great fan game like this and I hope it only gets better, you are doing a great job.
