atari- like game?

What are some tips on how to make your game look like it came from an atari 2600 console?

-Low detail Pixel Art
-Hard to control
-Endless
-chipmusic
-Something black on the screen

Dont know if this is the sort of stylization you want but this took me a day, has chiptunes and is endless. Dont think its that hard to control though!. http://www.jaboston.com/wreckingball/
