Neuralyzed is a browser game, an isometric roguelike you can play right in your web browser, either by hand with the keyboard or by letting a built in agent plan out an entire run for you. The core rules of the game, including combat, inventory, and randomness, are written in Rust and compiled to WebAssembly so they run fast inside the browser without needing anything installed. You control your character with arrow keys or letter keys for movement and diagonal movement, and there are keys for waiting, picking items up, opening your inventory, and firing weapons. Pressing the question mark key shows the full list of controls at any time. Instead of playing manually, you can choose a planning mode where the game searches ahead through possible outcomes and picks the strongest path, and there is also a mode that quickly tests your device and picks a planning depth that fits. The visuals come from a custom renderer built without a game engine, drawing the isometric world, character facing, and combat effects directly. The game can be played on the project's GitHub Pages site, run locally with Node.js or Bun, or built from source using Rust and Bun if you want to modify it yourself. The README is unusually detailed about how it was built: the developer used an AI coding assistant, GPT-5.6 through Codex CLI, to implement most of the engineering work, including the Rust simulation, the planning system, the renderer, and the asset pipeline, while the human author made the design decisions and reviewed the results. Artwork was generated with an AI image tool and then cleaned up with background removal software before being assembled into the game's visual atlas. The code and documentation are released under the MIT License, and the original artwork uses CC0, meaning it is placed in the public domain.
