Project Big Sphere

An early-stage FPS/TPS prototype exploring custom gravity on a spherical planet. Move freely across the planet surface, switch between first-person and third-person perspectives, and observe how movement, orientation, and the rotating sky respond to non-traditional gravity.

Overview

About this game

This project is an early-stage FPS/TPS prototype focused on experimenting with custom gravity simulation on a spherical environment.

Players can freely move across a small planet surface while gravity dynamically adjusts to the character’s position. The experience allows switching between first-person and third-person perspectives to observe how movement and camera behavior change under non-traditional gravity.

Current features include:

  • Free character movement across a spherical planet

  • Custom gravity simulation affecting movement and orientation

  • First-person and third-person camera modes

  • A rotating sky that reflects the player’s movement

This project is currently a technical and experimental build. It does not yet include combat, objectives, progression systems, or structured gameplay, and is intended as a foundation for future development.
