HTML5 prototype of a planet gravity platform using Phaser 4 and Arcade physics, written in TypeScript
A gravity-rotating movement system built with Phaser 4 and TypeScript, where a character walks around floating terrain by dynamically reassigning gravity instead of falling off edges. Movement and jumping are defined in surface space rather than world space, allowing seamless transitions around corners while keeping Arcade Physics fully in control.

Understanding QuadTrees: organizing space to reduce unnecessary work
QuadTrees organize space instead of objects, allowing spatial queries to skip large, irrelevant areas with a single check. This makes proximity searches and collision detection far more efficient in games and interactive applications. In this article, we explore how QuadTrees work and visualize them with a practical DOM-based example.

JavaScript Input Buffering: a simple project to show delayed keyboard events
In this post I’ll show you a simple but powerful JavaScript experiment that visualizes keyboard input in real time and with a one-second delay. It’s a small project built with pure HTML, CSS, and JavaScript, designed to teach essential concepts like keydown/keyup listeners, precise input timing, and requestAnimationFrame loops; the same fundamentals used in games, replays, and input debugging tools.
