This game would be great as a demo, as it stands it's mediocre and lacks the content to warrant evan a rental. The story mode can be beaten in 15 minutes and the game play is fun but lacks any challenge. Don't waste your time.
As an avid gamer and a product of 2d games thi is a poorly developed game. Without the choice to shoot in other directions other than forward, what more do i need to say. 10 minutes in, i am fast forwarding the lame and slow training dialog and the level are short and the difficulty for the bosses are insanely easy. Not to mention i just blasted through 7 level this game is garbage and weak at best don't do it unless you really are a mindless slave.
