# Gera o towercraft.pyxapp de Towercraft (Son Link (Alfonso Saavedra), GPL-3.0) a partir do commit 8c651f5 do
# repositorio son_link/Towercraft no Codeberg, com um patch nosso (publicado junto do fonte):
#   towercraft/quit-key-off.patch  a tecla que fecha o jogo no desktop (Esc) so congela a pagina na web; fica desligada.
# O .pyxapp leva so o que o jogo usa (towercraft.py e assets/, com a logo, a paleta, o .pyxres e as tres musicas
# em JSON), com o marcador de script inicial; zip deterministico (Builds/pyxapp.py): dois builds seguidos dao o
# mesmo sha256. (O towercraft.pyxapp do repositorio, para a versao online, nao e usado: o nosso sai do fonte.)
