You are Light Boy, smasher of shadows. Kill as many shadow monsters as you can before you die.
Shadow Smasher is a cross between a side-scrolling beat-em up and an Angry Birds-style physics game. Swipe and release anywhere on the screen to propel your character in the opposite direction. Your jump is also your weapon; attack by launching yourself at your enemies.
