On the Discover store, this looks like a fun little shooter. In execution, it is a very slow-paced shooter with a bit of Jetpack Joyride thrown in, but none of its excitement. The pace is really slow and there's a lot of input lag with the controls. It does look nice though, and the music is charming. As a free game, it's worth checking out if you've got kids around since it can be a fine distraction for them for a little while.
