Well Worth The $10
For fans of old school 2D-side-scrolling action, this game more than satisfies. In many ways it reminded me a cross between Megaman and Ninja Gaiden with the acquire an ability from the defeated foe/wall jump craziness. Brad's review is dead-on. I would simply add that there a few parts of the game that rely heavily on pattern recognition. If you are the type of person that can still finish the NES Ninja Gaiden without blinking, then this game will most definitely make you smile. Aside from the final boss fight which was a pain in the ass, I had a blast with this game. My only gripes are the length (but what do you expect from a $10 game) and the occasionally overly complex boss fight.
