Super Hammer Bros. 3 is a Super Mario Bros. 3 ROM hack created by Mitch "mitchflowerpower" Fowler as a joke.
The first "level" is merely just an unskippable Spade Panel. The player must go through that "level" to continue.
Following after is a group of Hammer Bro battles. Seven, to be exact. All consist of a battlefield made exactly like in World 1's only Hammer Bro battle in the original game and are shuffled up thanks to the first "level" of the game.
Six of their chests contain Jugem's Clouds, while only one of them contains a hammer, required to enter the final "battle" with Bowser and win the game.
My run breaks the system of luck and brainwashes the Hammer Bros to make the least amounts of movement possible for me to pass through. And in under a minute!
In case you don't know yet, I'm not too bright with luck manipulation. I'm sure it can be optimized a bit further for a faster time.
