Harmonics

Harmonics is a contemplative game made in 48h for Global Game Jam 2018.

You play as a pair of forest spirits that can explore various places on a magical floating island, and awaken flowers by singing to them. Flowers may awaken other flowers in turn, and cause chain reactions.

Ideally the game is coop (hence the two characters), where one player controls the movement with a joystick and one controls the singing by playing bass at a microphone.
