Until we can figure this out, please feel free to download it and give it a try that way! ;)
Hello again, I want to let you all know that the way I learned that you guys were misssing the UnityPlayer.dll file is from my experience trying your windows port. I am a GoDot Developer and had similar issues when exporting my project due to a file called index.pck being reported as missing, that until I relized it was a naming issue. As I don't use Unity please take what I said with a grain of salt. I hope you all find a solution to your issue, best of luck! -Dylan Griffey
