Cat Killer is an ominously-named new animal action game on iPhone and iPad. You play a rabbit who is wandering though a colourful, cel-shaded world filled with crystals to smash and cats to bash.

For some reason our rabbit hero has got some kind of blood feud with the felines and sets about dispatching them with nothing but a sword, and the ability to shoot plasma balls (why not?).

It just went live on the App Store, and we've played the first 10 minutes so you can check out the action without dirtying your hands with the blood of the cute and fluffy.
