All in the name of alpha testing  No worries like I said just as a suggestion when time permits I fully understand its a work in progress and in alpha stages.     

Well only reason I bring this up like myself have WinRar installed and Winrar can open .jar files. Can be confusing when somebody has similar setup installed and when they double click a .jar it wants to extract it. Not to mention theirs 8 jar files. 

I know this sounds like a dumb question but I think a needed question considering Notch posted a video of this on his twitter you might be getting some more traffic your way and could save you some time later on down the road. Some people might be confused on how to start and actually play this game. You just give them download for the files with no instructions, a huge pile of files with no .exes or anything. To somebody not skilled in java based games would be completely lost and would not know where to begin to start playing.

Just as a suggestion please add some sort of "How to play me" in a text document so your not bombarded with "ZOMG DOSENT WORK CANT INSTALL" or "HERP HOW TO INSTALL?" Love the game so far keep up the great work  .
