You do realize that there is a .exe in the package contents of the game.....
And you can't simply just cut Toribash down to "only" a .exe file.
I can't explain to much since my Toribash is structured differently than your's, I'm on a Mac.
Though can tell you that there won't be a release of Toribash that consist of Only one
.exe file that you can click and play.
Go to your Toribash, Right click it, then select "Show Package Contents"
and then you'll begin to understand it better.
