You only uploaded the executable, we also need the rest of the files that Unity gives you when you build the game in order to run it. These will include a Bandit King_data folder and unityPlayer.dll among others.
I've added the 64 bit Linux version to the downloads as my 64bit Ubuntu machine would not run the other one. In order to run it (and the 32 bit version), make sure you make the file executable (via 'chmod +x' or file properties).
