Looks interesting, I still have no friend so I can't check it out, but I am curious how did you make local network multiplayer in unity? For my last project I researched this topic but could not find anything that would work and just used Photon, since it is just easier and can be connected anywhere. Either way judging by the screenshots I would suggest to at least work on visuals a bit to get closer to the original. I am not sure if it is allowed in case of Buckshot, but using "utiny ripper" you can unpack most of the game into a project and use textures/models from there. And not to show of but I know how panful visual recreation can be, this is exactly what I did for my last project.
