Man, this game has a good premise but everything else is crap, no offense for a new creator but this needs a lot of work.
As others already mentioned, the arms movements are cringe, but I did likes the feet tapping and wobbling Not-Mihawk does.
The writing is atrocious, not only the bad English but the situations are awkward as hell, the girl could have stopped everything by just screaming, but she chooses to play asleep to be molested ? and then is happy to be saved, what if Not-Mihawk had gotten his sword and Killed the MC (who seems to have a MC syndrome ) for trying to play the hero?
Also we don't need 5 takes of the guy reaching Not-Mihawk to stop him, a single one grabbing his arm would be enough.
Also if he's supposed to be a famous Don what the fuck is he doing trying to molest girls in the train... it feels pathetic.
Overall, the dialogs need to be proofread or at least get some IA to run them and get something more coherent.
Chinzu getting in some comments from time to time also feels like telling rather than showing, we don't need us to be told that he dropped the bag we can see that.
I don't want to discourage the creator from his game, I do think he has a good premise but most of the game so far its bad, from wonky animation, to broken wrists to bad dialogue, this really need a lot of work.
Good luck with your project.
