Quarker
Descend through spacetime itself in this ASCII roguelike where the laws of quantum chromodynamics shape the dungeon. Quarks bind into hadrons, spacetime curves around mass, and the dungeon warps around you.

01. About
Why Eben Howard Matters Here
Game developer, open-source library author, and compliance-minded engineer. Best known for SquidLib, SquidSquad, and years of procedural generation work, with commercial credits that show the same attention to systems, quality, and shipping software well.
Roguelikes have been a passion since the earliest days — from ASCII corridors on an amber phosphor terminal to modern procedurally generated worlds with thousands of interacting systems. That love of the genre drives a constant search for better algorithms, cleaner abstractions, and more surprising emergent gameplay.
Beyond games, the same algorithmic mindset applies to platform engineering and GRC work: complex systems need robust, well-tested foundations. Whether it's a dungeon generator, release process, or compliance pipeline, the principles are the same.
