I assume you're talking about the remake of the first game? As far as I could tell, it seemed like a very faithful remake, so if you want the original experience but with better graphics, you'd probably enjoy it. I thought it was kind of blah, but I don't think that was the remake's fault so much as the original game's.
They've added an optional thingy that shows you where to go so you won't get lost, and you'll get to keep on playing even if you run out of time (though that may just be on the easiest difficulty setting, I'm not sure).
