The full story
Forest is a popular focus app: you plant a seed, a tree grows while you work, and it dies if you give up or leave. This Chinese project is a clean-room web version with zero dependencies. All trees are original SVGs drawn in code. The gameplay was written up first as a REA-style specification marking what was seen, inferred or unknown. It's also packaged as an Android app and a Windows desktop app.
