The 2 and a half stars i'm giving is for the music and artwork which I enjoyed a great deal. Other then that the repetitive button mashing, the small screen size, and the lag i'm getting really bring down the score on this. Also there was no point in a jump button.
Maybe if you gave it some level's for him to jump on, some side attacks for the jumping to make sense, a bigger screen and auto fire and this could be a smash hit.
