Since this is an open beta, i might as well bring this to the developers attention; the "mute Music" button in the options is hiding behind the account button, which makes it hard to press. I dont want to be a downer, i just want to make the game as good as possible!
Suggestion: The Map needs fixing, so it can be easier to navigate. This can be done be making your arrow stay in one place, and making the map rotate around it.
There should be an impossible badge called "Star Scream" (named after the transformer, and a play on words about frustration) where you must get a star on all the levels.
