Enter the surreal, disturbing, and ridiculous world of the Knobbly Crook in this old-school point and click adventure. O’Sirus the Snip is a simple paper farmer driven to epic adventure by a spooky face with a spookier voice. He will ultimately seek to become a Knobbcrookian royal guard–a Guffaloon. Stories of their heroic battles against the fearsome Bogold empire echo throughout the Crook. Unfortunately, they’re not currently recruiting simple paper farmers. He’s going to have to use every dirty trick in his book to cheat his way to the top and that means YOU will need to understand the key elements of the Knobbly Crook – Rock, Paper, and Scissors. Creatures of stone crush the metallic Knobbcrookians. The Knobbcrookians herd and farm paper animals. Fearsome stone giants fear tiny paper animals.

In the first chapter, The Horse You Sailed In On, O’Sirus finds himself on trial for all the crimes you have not yet committed. Retell his nonsensical story as his journey begins, finding himself a stowaway on a ship that is half horse, half boat, and half whale. Every moment that passes takes you further from your goal–the Knobbly Crook. It’s up to you to torment the Drafthorse’s unsuspecting crew in an attempt to alter their course.

The Knobbly Crook will be released in several chapters, all of them completely free. No ads, no tricks.


Gnarled Scar Manipulations is the creative label given to games and media within the world of the Knobbly Crook. My name is Ethan James Petty and I am the primary creative person working on these things (for the time being). I am the writer, artist, designer, scripter (currently working in the glorious Adventure Game Studio), grumbling voice actor, and sound designer for the Knobbly Crook series.

I haven’t been able to do it all alone. A good friend and industry vet, Julien Fullum, provides some of the concept sketches for the backgrounds. The wonderful soundtrack came from a generous free-to-use musician named Pitx. Many of the sound samples are also taken from skilled free-to-use artists (see credits). At times, I have recruited friends and family members to provide their voices as well.

A little bit about me: My first games came back in the shareware boom of the early 1990s, when I co-founded the “splatstick” indie game studio, Bloodlust Software. It was an answer to the censorship craze of that era and was intentionally gory, stupid, and offensive. You may remember me as Lord Hellbent Marstorious Deathspew IV. We created perhaps the worst (best worst?) fighting game of all time, Timeslaughter, and several other tasteless games. If they feel like crappy games made by high school students, it’s because they were crappy (but fun!) games made by high school students. At least we weren’t preps. The Bloodlust brand went on to work on small projects with Troma and, under the Bloodlust label, my programmer (Sardu) ended up working on emulators you may have heard of – NESticle, Callus, and Genecyst.

Later, I went on to work in QA/Level Design/Lead Design at Strategy First, where I worked primarily on the Disciples franchise, eventually leading the design team for Disciples 2: Rise of the Elves. I moved on to Ubisoft, where I have been working for 11 years. I started in Level Design (including Splinter Cell, Rainbow Six) and have since worked as a Scriptwriter (including Rainbow Six, Assassin’s Creed, Watch_Dogs, and Watch_Dogs 2).

While The Knobbly Crook series is “PG,” with dark humor, I am more potty-mouthed on twitter. I have a general rule that if you’re pleasant to me, I’m pleasant to you. So please feel free to come say hi, ask me questions, send me ideas, or share what you’re working on. I’d love to meet you!
