low-poly maze sphere 3d model

Low poly spherical maze designed for a puzzle video game. The maze is inside a hollow sphere where the player moves through corridors along the inner surface. The sphere contains simple labyrinth walls forming paths and dead ends. The structure should be clean and readable, with wide corridors suitable for a rolling ball player character. The model must be optimized for real-time game engines like Unity, with low polygon count and clean topology. The sphere should be a single game-ready asset with the pivot centered so the entire maze can rotate as one object during gameplay. Minimalistic low-poly style, no complex textures, neutral materials.
