Gamify the playing screen of Castle Breakout (iOS)

It occurred to me that something I like about other puzzle apps, such as the common Word games, is that you can see very readily your game level progress. As in on the given level that you are playing - you can tell how far you've got and how much remains. What I need is an icon on this main screen to show how much progress is remaining. I'm thinking maybe a key with circles around it that closes on progress??? Ditto on this tutorial screen that you see here - I need a progress meter to tick every time they make progress in the tutorial. My hopes for both these endeavors is to increase engagement or how much time a user sits with the app in the session....!!!!!
