Minor UI Updates for Clarity

Hi All,

Thanks for the initial feedback.  I've pushed a new update that removes the "Quit" button that was throwing a JavaScript error.  That was for my initially planned Windows build, it is not necessary when playing in the browser.  I have also updated the "Restart" button to read as "Restart Level" when you die.  I'm hoping this helps provide clarity in understanding that you will not restart from the beginning of the game, but rather the current level that you are on.

Thank you,

Kyle
