# Mudancas no jogo (xeonjia/xeonjia-fredygames.patch + xeonjia/sounds.py):
#  - sem links para fora: o menu Info perde Site, Doacao, Traducao, E-mail, Bugs, Codigo e Licenca (so Creditos, Versao
#    e as licencas de terceiros ficam), o pedido de doacao do final do jogo e o NPC da casa pos-jogo que cobra
#    doacao saem (hideDonationInfo/hideDonationWorker = true, o NPC fala outra fala que o jogo ja tem) e o pacote
#    url_launcher sai do pubspec (pubspec.lock acompanha: a build usa pub get --enforce-lockfile);
#  - na web as dicas de tecla mostram o teclado (X, Q, E, R), como no desktop;
#  - 7 efeitos sonoros (collision, damage, dialog, explosion, money, punch, snowball) sem credito de origem no
#    repositorio do autor sao trocados por sons nossos, sintetizados e dedicados ao dominio publico (CC0) por
#    xeonjia/sounds.py + o wav2ogg do projeto (artifacts/tools/pygame-music/wav2ogg, ver Builds/pygame-music/).
# A pasta web/ do projeto (PWA, manifest, icones, service worker) e trocada pelas pecas de flutter-web/.
#
# O fonte do autor vem por git no commit pinado (o GitLab nao serve tarball a robos); o tar.gz do fonte
# (git archive, gzip -n -9) e o que vai ao lado do jogo.
#
# Saida: artifacts/build/xeonjia-<commit>/{xeonjia-web.tar.gz, xeonjia-<commit>.tar.gz, SHA256SUMS}, conferidos pelo
# bundle.yaml do jogo.
