I'm a game developper trying to host my game on itch.
I followed this tutorial to upload my game using butler and everything went along smoothly: https://www.youtube.com/watch?v=PXyzYRNLd1I

But now I see that the itch.io app won't launch my game.

If I download the game without the app or if I navigate to the downloaded game's folders and click on the .exe file the game starts just fine. The problem occurs only with the itch app. (My game is built using Unity)
This is what I uploaded using this command line with Butler: 
butler push "E:\Unity Projects\Flash Project\BUILDS\UploadBuild\Braveless.zip" JeremyVansnick/Braveless:win

I must be doing something incorrectly but I don't know what it is. Any ideas?
