An absolute classic of a side scrolling beat-em-up. This game never got as much attention as it deserved, and brought me into the fantastic world of games made by Clover/Platinum like Bayonetta, Okami, Wonderful 101.
It's a truly unique game that harkens back to the days of power ranger/sentai super heroes, and has an equally awesome sequel game.
I'd love to see this game on GOG because I really believe that more people should be able to experience it, plus with Okami 2 coming, perhaps we'll finally get the long awaited Viewtiful Joe 3 as well!
