This is an excellent iteration of the Kid Icarus series, perfectly capturing the gameplay of the original Kid Icarus for the Nintendo Entertainment System, with some welcome tweaks to gameplay that make it an even more excellent title.  It is a little easier than the original, because of intelligent features like being able to move backward and forward in a level.  In the climbing levels it is nice to not die just because the screen moved above a platform.  I was really enjoying this game full of hearty joy, but then when I got to the fourth level my save game was lost.  That is what you'll want to check for as a buyer.  The save game feature worked great for me for quite a while, probably a week of consistent gaming.  Then I must have done something wrong when I was saving, because when I turned the game on, it wouldn't allow me to access the continue option.  Unfortunately, prior to listing this review I haven't gotten to the bottom of this problem, but I just want to offer this advice.  Play this game as soon as you get it.  If there is a saved game, good, that is a good sign, but then you should also play this game until you can save it at the end of the first level.  Save, then shut it down, turn it back on, and then see if your game is saved.  If so congratulations, you have purchased a good copy.  If not, then the seller has sold you a flawed copy, unless they specifically stated that the save feature doesn't work, then you'll want to see if the seller will issue a refund.  This should require you to mail the game to the seller who will issue the refund when they get the game.  If they let you keep it, you are lucky, but what have you gotten, besides a game that you cannot shut off if you want to get to the end of the game...
