Wow! You really put a big smile on my face with this one! First off: the game itself feels very polished... it is a nice little concept that keeps you playing for a while. However, you took that simple concept and created something fun and amazing out of it. To be honest, this is often the biggest challenge in game development, not making the most complex game but taking something simple, and make it enjoyable. You did this by the really fun sound effects, the refreshing theme, nice graphics and an overall nice look and feel. And as most others, I have to give this feedback as well: the sounds are amazing! With every new sound introduced, I was smiling more :).
