“Play Your Melody!” – MeloMisterio is a musical platform game where every action you take makes music. Steam page live now!

 Gentle Giants is pleased to share the release of the Steam page for musical improv 3D game “MeloMisterio – play your melody-”. Alongside a rhythm-inducing promotional trailer, the game is announced to be released on June 2026.

MeloMisterio is a 3D action game in which the player’s actions – such as jumping and dashing – become melodies. The game is built upon “interactive music” a concept in which sound changes according to the situation in the game. We aim to expand upon this and provide agency to the player who can create their own new sound experience solely through playing the game.

Director Shugo Tanaka majored in music composition at the Kunitachi College of Music, after which he went on to work on commercial rhythm games. He is currently in charge of programming, sound, visual direction and more. His aim is to create a new experience that blends music with gaming.

About MeloMisterio – play your melody-

Your actions become music! MeloMisterio is a musical improv 3D game where players must overcome obstacles through jumping and dashing. Each movement is accompanied by a sound and pitch change, automatically generating a melody. While many musical games reward rhythm and timing, MeloMisterio empowers your action to generate pleasant sounds that resonate with the world. Rather than operating in time with music, your actions are the music.

Solve puzzles by moving up and down the scale

Going up and down the scale doesn’t just make a sound. Picking the perfect pitch will allow you to move mechanisms such as raising and lowering lifts and lowering fences. Other musical puzzles include walls that move in time with the rhythm and finding treble clefs hidden in the stage.

This is a musical game that doesn’t require a sense of rhythm or knowledge of music composition! Follow our X for more updates and wishlist the game on Steam now!
