I highly recommend the demo as well.
I like the game, takes a little getting used to, but it's fun. Kind of like your average arcade game, shoot to kill, get to here as fast as possible, cause as much damage as possible. They do have a storyline to it, and when the game starts, they give you a very good tutorial of the buttons.
8/10. I would recommend this to others. Just think of Zelda on Game Boy to get a general idea.
