Get it. If you want old school hidden gem NES action, this game is a peach. Pretty darn hard too, but fun action/puzzler. I can't reccommend it enough, especially if you can save by freezing frame, would make it a little easier. Plus the music is kickbutt, even if it's really only one song!
I'm with you. It's a great classic that too many people have forgotten about. It was the second VC game I got after Mario 64. I recommend it to everyone.
I have 1000 points left and will be buying Kid Icarus and will seriously check this one out as well.
Ok, for those of you frustrated by the difficulty, here's a cheat that will help immensley in beating it. At the game over screen, hit Up+A+B to continue at the stage where you died (without your bonuses). That in combination with the save system on the wii should give you an immense advantage. Good luck.
