Third-party AI-generated assets

Pixel art in this project — characters, animations, obstacle sprites, and backdrop layers — is generated using PixelLab.ai. Those assets are governed by PixelLab’s Terms of Service and are not relicensed by this project. If you intend to reuse a specific PixelLab-generated asset from this repository, you are responsible for complying with PixelLab’s terms.

Tools used

• Claude Code — Anthropic’s Claude model, used for generating and editing game code, documentation, and configuration.
• PixelLab.ai — pixel art generation (characters, directional rotations, template animations, and map objects).
• Web Audio API — browser-native, used for all SFX and music. No audio files are shipped.
• Three.js (MIT) — loaded via the esm.sh CDN for the 3D game (Block Arena). Not bundled, not redistributed.
• Fonts — Geist, Instrument Serif, and JetBrains Mono, loaded via Google Fonts. All three are licensed under the SIL Open Font License.

Per-game credits

Running Man

• Character: PixelLab “Human Base” mannequin (1b27dde3-809d-47ca-8277-68bc6c5565b7), with template animations running-8-frames, running-jump, and falling-back-death (east direction).
• Obstacles: three PixelLab map-objects — rock, felled log, and cracked-road sprite.
• Backdrops: PixelLab map-object far-mountain silhouette, mid-distance pine forest banner, and three cloud variants.
• Audio: synthesized at runtime via the Web Audio API — no external audio files.
• Code: vanilla JS + Canvas2D, produced via Claude Code.

Neon Tower Defense

• Visuals: 100% code-drawn. Every tower, enemy, projectile, and effect is a geometric primitive rendered in render.js. No PixelLab, no images, no third-party art assets.
• Audio: synthesized at runtime via the Web Audio API.
• Code: vanilla JS + Canvas2D, produced via Claude Code.

Block Arena

• Visuals: 100% procedural geometry. Polygonal gun viewmodel, block enemies, arena pillars — all built from BoxGeometry + EdgesGeometry primitives. No textures, no models, no third-party art assets.
• Engine: Three.js 0.170.0 (MIT) loaded at runtime from esm.sh. Three.js is not redistributed by this repo — it is fetched by the browser from the CDN and remains under its upstream MIT license. See three.js LICENSE.
• Audio: synthesized at runtime via the Web Audio API.
• Code: vanilla ES modules + Three.js, produced via Claude Code.

Maze Runner

• Visuals: 100% code-drawn canvas primitives. Maze generated procedurally with the recursive-backtracker DFS algorithm and a Mulberry32 PRNG seeded by the user-provided string or number. No PixelLab, no images, no third-party art assets.
• Audio: synthesized at runtime via the Web Audio API.
• Code: vanilla JS + Canvas2D, produced via Claude Code.

Neon Blocks

• Genre: falling-block puzzle in the modern guideline lineage (SRS rotation, 7-piece bag, T-spin detection, ghost piece, hold). Mechanics are publicly documented and have been ruled uncopyrightable as game ideas (see Tetris Holding v. Xio Interactive, 2012). The visual presentation, naming, audio, and code are entirely original to this project.
• Visuals: 100% code-drawn canvas primitives. Neon-CRT aesthetic — scanlines, bloom, additive line-clear flashes, all drawn in render.js. No PixelLab, no images, no third-party art assets.
• Audio: synthesized at runtime via the Web Audio API. Layered music grows with level; no audio files shipped.
• Code: vanilla JS + Canvas2D, produced via Claude Code.

Idle Hoops RPG

• Theme: a generic idle basketball career simulator. No real-world basketball league names, team names, player likenesses, or logos are used. Player names are generated by combining a small pool of common first and last names; no real person is represented. There is no affiliation with, or endorsement by, any sports league.
• Visuals: 100% DOM UI with vanilla CSS — no canvas, no images. Player portraits are standard Unicode emoji. No PixelLab, no third-party art assets.
• Audio: none in v0.2 (reserved for a later milestone).
• Code: vanilla JS + DOM, produced via Claude Code.

Genre conventions & inspirations

Several games in this collection sit in well-established genres (falling-block puzzle, side-scroller, FPS, tower defense, idle / RPG). That is intentional — the project exists to showcase how AI tooling can produce fully original implementations of recognizable genres end-to-end, not to clone any specific commercial product.

Where a game implements a publicly documented spec (for example, Neon Blocks uses the SRS rotation system and standard kick tables), it does so because those are open, widely re-implemented genre conventions — not because any commercial source was copied. Game mechanics and rules are not subject to copyright in the U.S. (see Tetris Holding v. Xio Interactive, 2012, regarding the dividing line between uncopyrightable rules and protectable expression). The visual presentation, asset choices, code, and naming of every game in this repository are original to this project.
