# repositorio, com o patch blast-arena/web.patch: laco principal assincrono (pygbag), divisoes inteiras do Python 2,
# filter/map em lista, jogo renomeado para Blast Arena (nome e textos; o logotipo do menu foi redesenhado em
# blast-arena/gui_menu_background.png, CC0), sem a musica, configuracoes em /saves e "run away!" volta ao menu.

# afirmada no README do jogo), a fonte LibertySans (GPL "baseada na Liberation Serif", sem texto de licenca) trocada pela
# Liberation Sans 2.1.5 (OFL 1.1, com a licenca junto), logo.png, README, instalador e teste.
