Yeah, it has an easy mode. It also allows unlimited continues.
It's kind of weird but nice how it works: you can select unlimited continues, use credits to refill your health, and falling into a pit just sets you back to a checkpoint (the only penalty is that the timer doesn't reset when you go back to a checkpoint, so you can run out of time pretty easily if you're having trouble with a level). Kind of a nice way to experience a game that's pretty frustrating otherwise.
It also has the NA, JP and EU versions all available in the game. I don't even remember what the differences are, I just played the JP version tonight.
