Oops sorry about that, I exported it as "Pc Mac and linux standalone" in unity I don't know if that means it will work or not (I don't use linux)
I'll change it if it doesn't work (or release a post jam linux build if I can)
It's easy to miss in Unity, but in the Build Settings window you have to change the "Target Platform" and build each executable separately.
Got it! Thanks for helping me :)
