# Terarritweet — source provenance

Original 2D browser sandbox, inspired by the broad mining/building/survival genre. Not Terraria, not a Terraria port and not affiliated with Re-Logic. No Terraria source, proprietary textures, sounds, names or game assets are included.

Game code, procedural world, Canvas pixel graphics, animation and Web Audio effects were authored for this project with AI assistance. Includes the interrupted original Terarritweet terrain/physics/WS prototype. Licensed MIT: /LICENSE. Download source: /source.zip.

Runtime networking: ws 8.22.0, MIT, https://github.com/websockets/ws — license /licenses/ws.
Phaser 3.90.0, MIT, https://github.com/phaserjs/phaser — retained from the interrupted prototype as an unused installed dependency, NOT loaded by this Canvas client. License /licenses/phaser.
Browser QA: Playwright 1.56.1, Apache-2.0, https://github.com/microsoft/playwright — development dependency, not shipped to browsers.

Alternatives briefly checked: https://github.com/calimero-network/merraria (MIT verified through GitHub API). Its Calimero node/auth replication is not a drop-in authoritative WS backend. https://github.com/Mootbing/Fable-Test-Terraria license endpoint returned 404. No code/assets copied from either.

Woodland renderer (`public/art.mjs`): original procedural terrain, foliage, character, item and lighting artwork authored for this release, MIT. Visual direction was informed by inspected storyboard gameplay frames from the supplied YouTube guide; no screenshots, sprites, sounds or other proprietary assets from that guide are bundled.

Biomes release (`biomes-1`): original seven-material geological artwork, asymmetric chambers, local branching tunnels and a reversible fault trail. Fernwood, Amber dunes, Rootwild, Frostfold and basalt/crystal depths extend the world east to 2,400 × 320. This is not Terraria-equivalent generation. Every cell of the previous 1,200 × 320 rectangle is preserved on migration because historical edits cannot be proven from baseline comparisons alone. Camp remains near East 600. Generation is deterministic; accounts and valid saved positions do not shift. Save backups are private and are never included in the downloadable source.

All visuals and sounds are generated locally. No asset upload, external CDN, paid service or third-party login is needed. Anonymous inventory is tied to a random browser token. Shared terrain and inventory persist on this server; do not use this demo as secure storage. The free temporary Cloudflare tunnel has no uptime guarantee.
