The level design is incredibly layered! From simple "single-form challenges" to complex levels requiring the combination of multiple forms, the difficulty increases gradually. Beginners can quickly grasp the transformation logic, and once they are proficient, they can challenge high-difficulty hidden levels - such as solving puzzles by continuously switching between three forms within a time limit. After clearing the level, you can unlock new cool forms. The process of collecting different forms is incredibly satisfying and will ignite your collecting desire.
