One Hand Clapping

One Hand Clapping is a vocal 2D platformer in which you guide a traveler through a colorful world. Your microphone input is part of the controls: singing or humming changes the surroundings and helps you move forward.

Use changes in pitch, sustained notes, and rhythm to solve puzzles and navigate obstacles. Your voice can raise platforms, form paths, lift objects, and affect elements such as wind; some challenges also involve matching notes or making harmonies.

The journey spans six biomes, with three hermit characters offering guidance along the way. New vocal and musical challenges appear as you progress, and the settings let you adjust microphone sensitivity and your vocal range.

Players who enjoy the game often praise its unusual use of singing and humming as puzzle controls, finding it creative and engaging to make their own voices part of the world and music. Reviews also commonly appreciate the colorful art and gentle atmosphere, with some enjoying the story and its warm tone. Experiences vary: pitch recognition and audio delay frustrate some players, while others find the vocal challenges fun or manageable.
