the folder is a bit wack, you need unity.dll in the zipped folder, also the game data file has to be named a certain way. I succeded in copy/pasting unity.dll from another unity game, which worked, but then I tried renaming the data file but that didn't work. sorry I didn't get to play your game :( You could try downloading the zip file yourself to get all the error messeges, or just look up what is traditionally included in unity game zip files (i wouldn't know, i just barely played around with unity)
