Awesome game
This game is SUPER fun and I love getting medals so that is what I'm working on
One problem I'm having though is liking the facebook page, I like it however I receive no reward. I give this game a 10/10!

I have managed to unlock one of the secret medals. To get the first one you must beat a entire level with only yellow towers. I would suggest playing the first level "Daylight train".

Does anyone know how to unlock the second hidden medal?
