Please put a option in the menu

Please put a option into the menu that would put a cap on how many monsters can be spawned. I spent literally 2 years on a game, and it broke because I accidentally clicked a option on a command block. It tore me to pieces. I have been playing minecraft when creative mode was just added, please add it, please... Im still crying. Ill make a better review if you can fix this.
