You need to swipe your finger to move the puzzle pieces, and you need to aim and shoot at the cat enemy to rescue them.

The puzzle pieces will be moved to the target position by swiping your finger, and you will be able to rescue the cat if you are lucky. The cat will be moved to a new position, so you need to aim and shoot again to rescue it. If you are not lucky, the cat will be lost and you will have to start the game again.
