This is trying to be a recreation of the first Super Mario Bros game, everything goes well at first, until as you progress things get a bit rough.

It was renamed "SMB: King's Slaughter" because Koopa's Insanity would not make much sense. Originally it was going to be called "King's Carnage" (name suggested by: @PicoDigitalStudios
The controls are fixed. (I guess)
An improvement on most sprites.
I'm sorry to say this, but the easter eggs are not going to be there (except the Mario's secret level. You can access by typing "MARIO"), I'm still going to credit their exe-characters.
I have improved the atmosphere of the game.
Fixed the bug with character deaths (for example Luigi's death)
And I changed some messages.
The truth is that I tried to improve several things, I know it's not a big deal, but I hope you like it!
