A browser-based game built in TypeScript on WebGL2 with no game engine, libraries or asset files.

A synthwave endless runner which lives entirely in the browser. Built on WebGL2 with no game engine, no libraries and zero asset files. It's all TypeScript served by Vite, with a DOM/CSS neon HUD and the whole game compiles down to a 12 kilobytes of JavaScript.

The player is a glowing cyan cube racing across a neon ground line toward an ever-rising speed cap, jumping and double-jumping over spikes and blocks, diving under floating bars, clearing pits and moving past drones. Scoring rewards aggression; golden orbs chain a combo multiplier, shaving close to hazards pays bonuses, green orbs forgive mistakes and distance milestones, sector transitions and personal bests are celebrated. The controls carry a modern platformer feel and the run ends on a single hit, with your best score persisted in localStorage.

Everything on screen and in your ears is computed at runtime. The backdrop is a single procedural fragment shader; all gameplay objects are colored triangles rendered into one dynamic vertex buffer. Every 300 meters the entire palette rotates to a new sector. The soundtrack is a synthwave loop synthesized live by a WebAudio sequencer whose clock feeds back into the game to time the lasers and pulse the grid on the beat.

Below are the required software programs and instructions for installing and using this application on a Linux machine.

• Git

• Node.js

1. Install the above programs

2. Open a terminal

3. Clone this repository: git clone git@github.com:devbret/neon-run.git

This project repo is intended to demonstrate an ability to do the following:

• Deliver a complete browser-based game out of roughly 12 KB of JavaScript, with zero asset files

• Generate all pixels at runtime with raw WebGL2 shaders and no game engine or libraries

• Compose a soundtrack which is synthesized live by a WebAudio sequencer and whose beat feeds back into gameplay
