Insanely difficult but rewarding when you finally beat a level. I like the little cutscenes between worlds. Light on story and characters but the game controls so well that you probably won't care. This game's controls are fantastic and are the main reason this game became so popular. Most of the time you get the sense that failure was your own fault and not the result of something unfair. Worth a try but just remember that this game is intended to be difficult but fair.
