Discover a unique gaming experience on Project Big Sphere, an action-packed indie adventure by Joowon that lets you navigate a spherical world with first-person or third-person views. Witness how gravity-defying movements and rotating skies interact in this free-to-play prototype.
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.
