hi, I know this game I watched videos about it a few years ago.
to me it seems like the most important challenge when building such a game will be the animation, and the movement mechanism, while the online part will be easy as 100% accuracy isn't needed, I would suggest that you take a look at my profile and portfolio to see some of my previous unity work and some of my low-poly models, I believe this will be long project and lot of work and I think I will be the perfect candite for the job as am a passionate video games developer and expert with unity, and low-poly models.
just to be extra sure, I can build a demo for you for free, the demo will be a video of a demo project I will create, the demo project will have one character, will have the movement animation as in the original game and a very simple map, with a simple example of the online part (just the ability to see other players in the same game moving too) if you liked the demo then you can be sure I will be able to translate the concepts and ideas you have into a working game, if you didn't like the demo you can simply reject it with no cost at all, message me any time and let me know if you have any questions or if you want me to start working on the demo.
note the price I included is for the whole project, as I think this will be more convenient for both of us, instead of the hours-based amount so it will be 500.00$ USD for the work of around 2 months.
