Mr.Pig game play

I have finished the whole book on “3D Apple Games by Tutorials”, but I when I build and run on a device the game moves kind of slow. the main downside is how mr.pig himself jumps to slow, and doesn’t respond to gestures well. Is this something anyone has come across, or is it just not made well, or something?? I know it isn’t my device, for I have a 32 gig iPad Air.
Any ideas??
