Summary: When I first bought this I thought "Woah this must be cool". But when I played it I lost so many times and it killed half of my brain cells so now I don't know what 1 + 1 is... Then I got so angry I poured water on it, stomped on it, threw it at the wall, then snapped it in half! So save your money and buy Kirby: Canvas Curse!
Conclusion: This game really could have been a half decent 1st person shooter for the DS but it's let down by very poor collision detection. I could go on and say what's good about it but when something as important as being able to hit the things you shoot is broken what's the point?
