generic game that quits when you lose

OK SO YOU ARE A RED CUBE THATS ALWAYS MOVING FORWARD AND YOU CANT STOP..... YOU NEED TO DODGE SCARY EVIL BOXES BY USING THE "A" AND "D" KEYS ON THE KEYBOARD YOU ARE USING TO MOVE LEFT AND RIGHT. IF YOU FALL OFF THE EDGE OR HIT A BOX THEN YOU LOSE.

OH AND YOU DONT WANT TO KNOW WHAT HAPEPENDS WHEN YOU LOSE...
