About This Game

REMEMBER WHAT WAS TAKEN FROM YOU

polymorphite is a rhythm-adventure hybrid game that fuses keyboard-and-mouse rhythm dodging gameplay with a deep narrative following three concurrent Tokyo residents as a bizarre serial murder case unravels the fabric of reality; and the question of what it means to be “human” becomes more important than ever before.

polymorphite is played with one hand on the keyboard and one hand on the mouse. Notes of various types will fall down from the top of the screen, and it’s up to you to make sure they get decrypted properly! Move the mouse to dodge hazards and collect special kinds of notes as you whittle down the opposing Data Block’s decryption bar to clear the stage.

With a wide variety of difficulty levels for all kinds of players from rhythm game beginner to note stream master, everyone can progress through the story of polymorphite with enough trial, error, and growing stronger through each stage.

polymorphite features a rich character building and customization system. Obtain modules by playing songs in rhythm game mode to materialize unique “Concepts” which can be equipped to your characters to influence their stats and capabilities within gameplay.

Characters also become stronger through the original Aspect system. Unlock strong Cores through the story to develop into Aspects in a board-game style progression mode.
