Ensure smooth operation on various devices: It's crucial to optimize 3D assets because the game will run on different smartphones and tablets. Controlling the complexity and size of models is necessary to ensure the game performs well on diverse devices.

Adapt to real-world augmented reality experiences: Since the game's core is augmented reality, it's essential to ensure that 3D assets appear natural within real-world environments. Considering various lighting conditions is important to ensure virtual objects seamlessly integrate with the real world.

Create visually impactful effects: The game aims to frighten players, so the design and animation of 3D assets need to be sufficiently terrifying. Ensuring that monsters, scenes, and other elements create an intense and thrilling atmosphere is crucial.

Don't compromise performance with animations and effects: Using appropriate animations and visual effects to intensify the fear factor is important, but it's equally crucial to avoid negatively impacting the game's performance.

Integration with augmented reality technology: Effective integration of 3D assets with augmented reality technology is essential for accurate mapping, tracking, and interaction of virtual elements. Collaborating closely with AR engines or libraries is necessary for this integration.
