Progression

Versions

// how every model, graphic and sound has changed over time

Each asset keeps all of its versions. Newest is on the right, marked Current.

01Models

02Graphics

03Sounds

Sounds that have been replaced. Every other sound on the Sounds page is still on its first version (added 2026-10-12).

04How it's tracked

All history lives in one file, assets/versions.js. Every page reads it, so a new version shows up everywhere at once.
Before an asset changes, its old render or sound file is kept in assets/versions/ and its old code is archived in tools/legacy/, so any version can be re-rendered or re-played later.
v1 assets here were rebuilt from the original 2026-10-11 code; the v1 graphics are real screenshots of that build.
