HTML5 prototype of a planet gravity platform using Phaser 4 and Arcade physics, written in TypeScript

This technical article details the development of an HTML5 game prototype featuring a character walking on a platform with rotating gravity. Using Phaser 4 and Arcade Physics in TypeScript, it explains how to implement movement in 'surface space' instead of world space, allowing the player to transition between sides of a terrain seamlessly. The post includes code snippets and discusses the core logic for tracking walking sides and reassigning gravity dynamically.
