The Howler is a puzzle platformer with a twist. While it's possible to control the game with a good ol' mouse and keyboard, it can also be controlled entirely by voice. The goal is to guide a hot air balloon through wind currents in order to reach different objectives.
Players can raise and lower the balloon by modulating the volume of their voice, and even drop bombs by making short, loud noises (yelling "bomb" seems ideal). Watching the trailer, we think we might know where developer Marcelionis came up with the game's name. You can pick it up from Desura on PC or Mac for $5.
Side note: If you've been looking for a game to help you practice that one scene from Aimelie, The Howler is perfect.
