Boots and the Black Cauldron

LittleJS - The Tiny Fast JavaScript Game Engine Special Js13k Branch LittleJS is a fast, lightweight, and fully open source HTML5 game engine designed for simplicity and performance. The code is clean and well documented with some fun examples to get you started right away. The starter project builds to a 7kb zip file and includes all of the primary engine features.

Boots and the Black Cauldron was submitted to the js13kGames 2025 competition by Raptor Dev and Noah-Zark-22. It earned competition recognition. Like every js13k entry, the entire game — code, art, and audio — fits in 13 kilobytes, a constraint that rewards focused, clever design over bulk. Individual features like WebGL can be disabled to save even more space.
