A Super Mario ROM Hack aggregator/archive thing

Keratin Valley

Released:
By: Revolug
Found on: smwc
Difficulty: 10

This is a strange and extremely difficult romhack that I’ve been working for far too long.

It features five shell levels connected through a vast and sprawling hub-level that requires puzzle solving, exploration, and precision platforming. Each level opens up more paths and possibilities for navigation. Be sure to take notes of significant landmarks and objects, as you might need to revisit them at a later point. If you’re ever stuck, don’t feel bad about asking for help, whether it be from others or from me.

The shell levels included in this romhack are some of the most challenging levels I have ever played or created, but I hope they are enjoyable nonetheless. Practice sections have been included for those too stubborn to savestate practice. Please use them if you value your time and sanity.

Clear video for all the main levels (No hub-level solutions included): https://www.youtube.com/watch?v=taFjn_da7FU

(Note, the clear vid has some tiny differences due to being a pre-playtesting version. Shouldn’t affect gameplay too much.)

Additional information:

  • Checkpoints autosave.
  • Gray shells don’t collide with any sprites.
  • Winged yoshi can fly by holding the jump button down.
  • Start-select is enabled.
  • Switch blocks do not contain powerups.

Good luck and may you find your way in the valley.

Update 1.1: Fixed a major sequence break, made some hub-world gameplay changes to make things more readable/fair

Update 1.2: Fixed cheese in “Shaolin Monk Motherfunk”, fixed an error with one of the practice sections

Update 1.3: Various decheeses, fixed a softlock at the credits.
