# Mudancas no jogo: nenhuma no codigo nem nos dados. A build e a do `make wasm` do projeto (./cmd/linefire, GOOS=js GOARCH=wasm), com os
# flags de release dos outros jogos em Go do site; os mapas, os assets vetoriais e as 3 musicas (geradas com IA, ver music/README.md do
# projeto) entram no binario pelo go:embed do proprio jogo. Os efeitos sonoros sao sintetizados pelo jogo (biblioteca gion).
