Luís Moreira and Pedro Almeida.
By the time We did this game We used a web server (that it's not available anymore) for managing our login entries. I've edited a little bit so You can now test it out by login in typing the username 'admin' and password 'admin': feel free to edit our code ! By the same reason mencioned above You can't play on Multiplayer mode: only Singleplayer mode is working.
Enjoy and have fun !
