MONOWAVE is a puzzle adventure in which a newborn Guardian spirit named Mono reunites four scattered Emotions, using a different power for each one across four realms.

MONOWAVE is a puzzle adventure game that follows Mono, a newborn Guardian spirit charged with protecting four Emotions: Anger, Anxiety, Happiness and Sorrow. The Emotions were once nurtured by the Prism Tree at the centre of the world. When the Emotion Shards inside the Prism vanished, the Emotions were scattered across the land and the tree began to wither. The player guides Mono in bringing the Emotions back together and restoring harmony.

Gameplay centres on four emotion-based powers. Happiness allows the player to jump to greater heights. Sorrow lets Mono melt down to pass through narrow gaps. Anger enables wall-jumping, and Anxiety provides heightened senses for avoiding threats and crossing difficult terrain. The player can also share emotions with other spirits to change their behaviour and solve puzzles, and the characters in the world react to the player’s powers in different ways.

The game takes place across four realms, each shaped by its ruling Emotion, with settings that include foggy jungles and blazing caverns. Its art style is based on the look of scratch art, and it features an original soundtrack. MONOWAVE can be played alone or in local two-player co-op, and Steam Remote Play Together supports online play with a friend. Two-player mode requires at least one controller.
