A native binary will be much apreciatted. please..please. Since you're using Unity is just a few clicks aways to build it.
Have you ever thought about evolving this? add more levels, enemies, goals, weapons, plot,... I can help.
Yes...maybe it's a dificult task each platform has its icons, and a diferent way to sign executales and pack resources. A windows would be the less effort binary as my expertice tells me. I even made a little review here : https://threepixels.org/jak/index.php?ID=415
