Even though I'm a newbie, I like the game and it reminds me of robotron and smash TV which are games I enjoyed in the arcade, plus I think I have them on my XBOX 360 in a Midway Bundle. I'm glad I took a chance on the game.

How many worlds are there? I just can barely clear world 1 on easy / arcade with no continues. I'm slowly learning world 2.

Any thoughts about the game? Advice?
