Add Scoreboard To iPhone App

Hello! Super Simple Project! I have a game in the apple store called Oblivious. You should go and check it out. Currently it has no scoreboard/score. I need one of you guys to add a good looking score that adds 1 point for every second your alive. It would also have a high score that would be shown at the title screen. This is programmed in SpriteKit and does NOT use storyboards for the title and game. You will need to program a spot for high score and score! CANNOT PAY MORE THAN $20
