If you have a 5200 and do not own this title, then you're missing out. This is the bug-fixed version of the original 8-bit mega hit, and it benefits considerably from the 5200's analog control.

The only way it could be improved would be to allow dual control usage, so that one player could use the joystick and fire buttons, while the other handled the keypad. That would allow two people to play the game cooperatively at a very low coding cost.

Otherwise, this implementation is flawless and belongs in every 5200 owner's collection.
