# Gera o bit-maze.pyxapp do Pyxel Bit Maze (Takane Ichinose, MIT) a partir do commit 9addcf7 do repositorio, com um
# patch de uma linha (bit-maze/no-quit-key.patch: sem tecla de sair, que na web so congela a pagina): o .pyxapp
# leva so o que o jogo usa (bit_maze.py, scenes/, objects/, utils/,
# assets/bit_maze.pyxres) mais o LICENSE (MIT exige o aviso junto das copias), com o marcador de script inicial.
# Zip deterministico (Builds/pyxapp.py): dois builds seguidos dao o mesmo sha256.
