I think I've run into the problem you're build files are having before.  Sharing Mac builds is difficult, and if you rename the app or zip file it will break the unpacking process for the other users.  Make sure to build the app with the name you want to distribute as, and when you zip it don't rename the zip.

Hi, I tried to play it too but without success...

Hey, I just downloaded this but dunno how to run it; is there an exe in the zip files somewhere?
