I would really like to play your game, but unfortunately I cannot play it. :(
In order to play a game built with Unity you need the other files in the build folder as well (not just the .exe file). For example, for my game 'Rocketjumper' I need all these files to be able to run it:
All these should be in the .zip file that you upload.
Let me know if you fix it! I would love to try your game :)
