After Burner II
Though After Burner II is translated fairly well, it suffers most at the hands of the control scheme, which loses a lot of value on the scaled-down mobile system.
Those looking for a game with lots of challenge and a distinct sense of style would do well to check out Shinobi.
Take the helm of the spaceship Opa-Opa and blast your way through countless enemies as you journey through fantastical levels.
The sprites may be smaller, but the spirit of the classic shoot-'em-up, as well as its original level designs, remains intact.
