Provides an accessible, browser-native 3D platformer game experience directly from the Chrome toolbar without needing to visit external gaming websites or install desktop applications. Works offline for single-player mode.

User clicks the Chrome extension icon to open the game popup. The main menu displays with volume controls, fullscreen option, Discord link, and a Play button. Clicking Play loads the 3D game (v1/index.html) built with Three.js and Rapier physics (WASM). Player selects levels from the campaign or community packs, controls a cube character through 3D obstacle courses, and can participate in online multiplayer races. Level editor allows creating and sharing custom levels.

Target users: Casual gamers looking for quick browser-based entertainment / Speedrunners who want to compete on leaderboards / Creative players who enjoy building and sharing custom levels / Chrome users seeking a lightweight offline-capable game

The extension source is heavily minified/bundled (303 files, largest JS file is 848KB), making deep code analysis challenging but the overall structure and functionality are clear.
Multiplayer implementation details are embedded in bundled WebRTC libraries and could not be fully traced, but no authentication requirement was found.
The 'pro' naming in SVG asset filenames (button-play-pro.svg) and audio files (boxel-3d-pro.ogg) could not be fully explained but no paid gating mechanism was found in the code.

Monetization

No paid features detected

No payment infrastructure detected anywhere in the extension. Zero matches for premium, purchase, pricing, payment, stripe, billing, or in-app purchase. All 'pro' keyword hits are false positives in WebGL shader code (projectionMatrix, projTexCoord, process, RECIPROCAL_PI) and library internals. The file 'svg/button-play-pro.svg' is simply the visual design asset for the regular 'Play' button (the main menu code shows it navigates to the game with no payment gate). The 'upgrade' keyword only appears in a changelog entry about upgrading a physics engine library version. The extension has no feature gating, no payment platform integration, and no upgrade prompts. The game is entirely free to play.

Reason: The extension is a self-contained 3D game that runs locally in the browser popup. The manifest only requests 'storage' and 'unlimitedStorage' permissions. The main application code (main-CkUTk6PW.js) contains no login UI, authentication flows, or account management. All keyword hits for 'login', 'signin', 'account', 'auth', 'session', 'token', 'jwt' are false positives: 'jwt' appears in base64-encoded metadata (verified_contents.json), 'account' appears in GLSL shader comments ('account for clip-space aspect ratio'), 'sign in' appears as WebGL shader port notes ('Changed sign in W component'), 'session' appears in WebRTC SDP handling for peer-to-peer multiplayer (not user accounts), and 'auth' appears in level JSON files as 'author' field names. The multiplayer feature uses WebRTC for peer connections without requiring user authentication. No external authentication hosts were detected.
