# Mudancas no projeto Bugged Racing (esensar/bugged-racing, commit de0f97c) feitas por build-bugged-racing.sh:
#   1. O multiplayer em rede (ENet) sai: network/multiplayer_controller.gd vira um autoload offline (so is_online()
#      = false, peers vazio e o sinal peers_updated, que o resto do jogo consulta), menu/multiplayer_menu.* e o
#      botao "Multiplayer" do menu principal somem.
#   2. O menu principal perde o botao "Exit" (nao faz nada na web) e a fileira "Built with" com os logos do
#      Godot, Blender, Krita e Kenney, cujos botoes abriam sites externos (OS.shell_open).
#   3. Os links da tela "About" (OS.shell_open) deixam de abrir paginas; o texto e os creditos ficam.
#   4. O campo "Multiplayer name" das opcoes vira "Player name".
# Uso: python3 -I patch.py <pasta do projeto>
