Plain physics can be weird in this game. The wonky physics sometimes things bounce unpredictably or it's hard to aim and i think the controls can feel weird.
Step and swipe to aim and shoot at the hearts, watch out for obstacles.
Controls are taps and swipes. A specific feature is the auto-aim that you can wait for to get a better shot.
Try aiming slightly above the hearts instead of directly at them. Most of the time slow and steady works more often then not.
