console replays keystrokes after exit...

[beta-tester]

when i leave/exit penguinspuzzle the console replays all keystrokes made during gameplay.
that causes unexpected behaviours bacause the bash history may start old commands - depending what is in the history and what keys you pressed during the game play.

environment:
RPi B+,
started penguinspuzzle from console (not from startx terminal).
i used the preinstalled penguinspuzzle from the offician RaspberryPi image (2014-06-20) (http://downloads.raspberrypi.org/raspbian_latest)
