The mission for this game is to destroy all the sadness throughout 36 levels. To accomplish this mission, you must use your arsenal of baked goods to destroy the sadness. It's an all around sweet concept. Who wouldn't want to cure the world of sadness with donuts and cupcakes? The game has a retro look to it and a simple gameplay. There are no in-app purchases. You can earn and upgrade your weapons throughout the levels and worlds. The soundtrack will get stuck in your head if you let it. This really is a fun experience with a simple concept that is a throwback to the 16-bit games of long ago.
