From Studio BBB:
MONOWAVE sees Mono reunite the scattered Emotions one by one, each changing how they navigate and interact with the world. Anxiety lets Mono sense traps, Anger enables wall-jumps, Sorrow lets them melt through narrow gaps, and Happiness increases their jump height. As the adventure progresses, these abilities evolve further, giving Mono new ways to explore and overcome the challenges they encounter.
Mono's abilities extend beyond movement, with the game's 18 spirits each reacting differently to their current Emotion. By singing to nearby spirits, players can experiment with Anxiety, Anger, Sorrow and Happiness to discover 72 possible interactions that can affect puzzles and traversal. The four major boss encounters are similarly shaped by their ruling Emotion, putting players' understanding of each Emotion to the test.
Beyond the main adventure, MONOWAVE features eight hidden stages, with two secret stages in each of its four main regions, alongside dedicated Codices covering spirits, environments, worlds and the four Emotion Spirits. Together, these optional discoveries offer plenty of opportunities to uncover more of MONOWAVE's world and the emotions that shape it.
“We wanted players to experience emotions and empathy through play,” said Gwonyeong Lim, CEO of Studio BBB. “In MONOWAVE, paying attention to how a spirit feels can help you find a way forward. We hope players enjoy discovering those connections, whether they’re playing on their own or sharing the adventure with someone else.”
