Unfortunatly I haven't been given the code so I can't test it out. TBH I don't think this was even meant to be leaked without permission. If there was proper permission for this game to be leaked Spiderzsoft would have replied to all of us with codes.
Anyway I looked into the Unity assets, and it's definitely genuine, (music/sprites etc). Just cannot run it without the converted code. There's a few of these games that heavily rely on your hardware ID unless it's unencrypted like Crossy Road.
