This project is a browser-based recreation of Agar.io, designed to explore real-time interaction, game mechanics, and front-end performance. Built using JavaScript and HTML canvas, the game simulates player movement, object consumption, and scaling behavior within a dynamic environment.

Recreated core Agar.io mechanics while implementing real-time rendering, practicing game loop and animation logic, building scalable interaction systems, and improving browser performance.
Analyzed how Agar.io handles movement, scaling, and interactions; defined core mechanics (movement, spawning, growth, collisions); and fine-tuned sensitivity, scaling, and object density for smoother gameplay.
Games like Agar.io use simple mechanics and real-time interaction to drive engagement, but can become repetitive, and many alternatives prioritize competition over clarity. This project builds on their fast, intuitive gameplay while improving design, onboarding, and overall user experience.
I wanted to challenge myself to build a more complex interactive system that required real-time updates, continuous rendering, and user input handling. Unlike static web experiences, this project required managing multiple moving elements and simulating game-like behavior in the browser.
The goal was to recreate the core mechanics of Agar.io in a simplified, single-player format. Players control a cell that grows by consuming smaller objects while navigating around the game space.
