Every time I update something, I worry if I have done enough regression testing. 

"Please don't break. Please don't break."

• Gave more instructions on start up, especially how you can CALL PEL for hints
• Fixed some spelling mistakes
• Changed Puzzle 1 again, hopefully to make it more clear
• Changed Puzzle 4 to make CALLING PEL more clear for hints

And I updated beta testers! I think it's almost ready to be moved to an official V1.0.0!
