I have been playing this for a while now and its a great game.
My only complaint I have is that once you complete a level and then go back to it , the game clears the number of stars for that level. If I finish a level with X stars, the highest star total should anyways be displayed on the level select screen. A few times I have finished a hard level with 5 stars, then either myself or someone else using my phone clicks on that level again and erases my score
