Monowave is a platform and puzzle game with a poetic style, released on September 16, 2026, for 8.99 € on the eShop. Developed by Studio BBB, a young independent studio based in Seoul, South Korea, this is the studio’s first game. Before Monowave, the team participated in two South Korean events: the Gyeonggi Global Center in 2024 and the Kocca Indie Game in 2025. The game is published by Phoenixx Inc., a Tokyo-based publisher founded in October 2019 by former members of Unties, an independent branch of Sony Music Entertainment Japan. Phoenixx Inc. focuses on supporting independent creators both in Japan and internationally. In Monowave, players control a small creature named Mono, who can emit sound waves to influence emotions and solve puzzles. The story follows a world where a Prism Tree once distributed colors evenly to all inhabitants. However, a group of troublemakers stole the four colors, causing the Tree to wither and plunging the Spirit World into chaos. To restore balance, the Tree creates Mono, who must recover each color by navigating through various challenges. Each emotion—happiness, sadness, anger, and anxiety—gives Mono unique abilities, such as jumping higher, sneaking through tight spaces, or becoming immune to certain dangers. These emotions are obtained by interacting with creatures or flowers that match the emotion’s color. The creatures, called Spirits, are not true enemies. Their behavior changes based on the emotion they feel. Some manipulate the environment, like breaking walls or digging tunnels, while others assist the player by launching them into the air. To transfer an emotion, players must sing, which allows them to switch states and share feelings with the Spirits. While this mechanic can feel repetitive due to the need to maintain the action for a few seconds, the game’s design ensures that players must first obtain the right emotion before using it, which adds a layer of strategy. The game features a 2D world map similar to Super Mario World, allowing players to revisit previous levels at any time. Each world focuses on a specific emotion and includes a boss battle that requires solving a puzzle by transmitting the three missing emotions to the boss. The visual style is charming and unique, resembling childhood drawings with a polished aesthetic. Each world is colored to reflect its emotion, from a blue, dry forest for anxiety to a red, volcanic landscape for anger. The music and sound design are also centered around emotions, with each state having its own distinct atmosphere, enhancing the game’s immersive experience.
