You could make it kind of like Tower defense. Patrick has like 3 lives and he goes through levels. You could put things like lasers and evil guys that hurt him and once he's hurt 5 times he dies. You could make him get all the cones, go the the "door" and progress then to the next level. Finally when you finish the game you could put up a sign that says "You win!! Congratulations" If you don't want to do it that way you don't have to, I'm just giving you suggestions.
