         | those you fail to defend against) modify the game code, causing
         | surprising behaviour.

           | Yup, Missile Command, but the game code is located in bottom
           | of the bitmap ('frame buffer' if you like), so when the line
           | drawing code writes to that area it will modify it.
           | Shenanigans!
           | 
           | The bitmap would end before $3fff though, since it's only
           | 8000 pixels.

         | The visible text in the GIF is:                 $2000-$3fff was
         | made for the Ludum Dare       #31 Game Jam in December 2014. It
         | is       actually more than just a game. Some of       you will
         | say it's crap, but we would       point out that it's both a
         | game and a       piece of art. The idea and concept is
         | actually great:            This is the official description of
         | the       game:            "$2000-$3fff is a Commodore 64
         | program       which displays its entire memory on the
         | screen, then draws missiles into it.            Use a joystick
         | in port 1 to target your       dangerous explosive weapon. If
         | you       don't have a C64 handy, feel free to       use an
         | emulator like VICE.            Defend program data and program
