Wandersong

Wandersong is a side-scrolling puzzle and adventure game that uses music as a puzzle-solving mechanic. The player character can sing to cause events to occur in the environment around them, using a coloured "song wheel" with eight directions, each representing musical notes spanning an octave, which is controlled by the mouse on a computer setup, or the right thumbstick on a controller. Certain challenges in the game involve the player matching notes or tunes with a non-player character's song, similar to a typical rhythm game. Functions that allow the player to perform dances also exist, but do not actually serve a purpose in gameplay. Wandersong is set in a universe created by a goddess named Eya who "sang the universe into existence." Every epoch, Eya sings a brand new song that destroys the universe and creates a new one. The player character, known as The Bard, makes an attempt to gather the pieces of the "Earthsong", a composition that, when sung, will allow the universe to be preserved. The game is estimated to be 14 hours in length.
