When uploading Unity games, the entire build folder needs to be compressed and uploaded. The executable will search for a UnityPlayer.dll file and data folder, and in this case, it won't find one and won't run :(

From the screenshots alone, this game looks cool though. If you upload a version with the required files, I'd like to check it out in the future!

The game wont run. And the download is really small for a unity game.
