There's progress in the game mate. You have to tap on the click on the play button on the top right corner after getting 1 star. When you clear the of trash, it will also take you to the next level.

Oh I see it now! I'm sorry. Once I cleared 2 levels I thought the 3rd level was quite entertaining - having to pickup trash in secret without getting caught by the guards. I was getting the idea the light rays showed where the guards were looking so you had to stay out of them, which was I thought was an interesting and unique challenge. Quite fun, thank you!
