CASTLE MARIO BROS 3.
This is a very difficult SMB3 hack, it is as hard as Kawa with an added time calculation difficulty. It has only 8 missions (castles including Bowser's) that creator does not want anybody to pass. Specially castle number 7.
Please enjoy playing this hack as the author was creating it.
Best wishes and long live to SMB3 Hack game players.
Note: This is a Mexican hack so the texts inside the game are in Spanish.
