I was thinking everytime you complete a level you get another life... as the levels are harder there is alot of times they arent beat within the 5 lives given. so when you beat a level you get an extra life, or maybe a point system. after x amounts of points you receive for completing a level you get an extra life. (x amount shouldn't be excessive) also the time before another life is given should be shorter or make the piggy bank free to empty. everything on this game cost something. and I understand profits, buy something should be free not everything obviously but something.
