I downloaded your file and found it has only an executable that won't run in Linux. For that, I think you should only mark it as windows build.
I would love to play your game so if you made a Linux or web build, let me know :)
Ah my bad, I thought the initial unity build would work on linux. I don't have a dedicated linux machine to test this either so for now it will have to wait. Thank you for checking the game out though!
Not at all. Good luck :)
