Gangsters & Gargoyles
Gangsters & Gargoyles

As the ancient manors of a lost age sink into the bayou, the gargoyles who once prowled their eaves must find new habitats. Many come to Mad City, taking jobs as night watchmen or chasing alleycats for sustenance. On still nights, they can be heard: gurgling, weeping, moaning. Many talk of the proud manor houses they were forced to leave behind. Your party has befriended one such Gargoyle, an ugly wee thing named Firebrand. Godfather Gordon’s gang has seized Firebrand’s former home. They’re slowly demolishing the house as they search for the treasure Firebrand was created to guard: the Gargoyle’s Glove. Firebrand no longer cares to guard the treasure; he just wants to keep it out of Gordon’s hands. If you can retrieve it, you can keep it! It is said that no castle can stand against its power. Firebrand hopes that you wipe out Gordon’s gang in the process. Accept the Gargoyle’s Quest! Enter the bayou and retrieve the Gargoyle’s Glove! Inspirations Adventures of Bayou Billy The source of most NPCs and enemies. We also drew inspiration from the game’s structure: levels are a mix of beat-‘em-ups and rail shooters. These rail shooter segments used the NES Zapper, which inspired our gangsters’ weapon of choice. Mad City, our home base, is inspired by the game’s Japanese title. Gargoyle’s Quest II The inspiration for the Quest Giver, the dungeon’s fiercest monster, the Blacklight random encounter, and the gargoyle-festooned aesthetic. Super Glove Ball The source of our two MacGuffins. We were inspired by both the Breakout-style gameplay, where you navigate a maze by destroying walls, and the PowerGlove peripheral itself. Acknowledgements Writing by Austin HolmLayout and Editing by Gabriel WatcherIllustrations by Ja-Ki Barnes We are so grateful that we get to play and create on the unceded traditional territories of the Musqueam, Squamish, and Tsleil-Waututh Nations.

The Horrible Harusame Castle
The Horrible Harusame Castle

The lightning strikes. The clouds shift. The faint voices of a choir sound. A city on the edge of psychic disaster cries out for its unlikely saviors. Ninjas? Aliens? Ghosts? Rad dudes with bad ‘tudes? What secrets await you within the walls of Harusame Castle? Tasty megadungeon gameplay compatible with the Shadowdark Entertainment System! Five (5) thrilling levels of hardcore neo-feudal combat! Zillions of items and treasures from the humble town of Fieldspring! Allies with unfamiliar faces, and wild baddies for bustin’! New Hit Count and spooky Ghostly mechanics make it feel like it’s real! Don’t delay, play today, or the bland seasons will pass for so long…                               The Horrible Harusame Castle was created for the 2026 Shadowdark 8-Bit Game Jam. Our assigned inspiration games were The Simpsons: Bart vs the Space Mutants, Ghostbusters, and The Mysterious Murasame Castle. Our toughest constraint in this jam was the page limit, as we felt we had well over 16 pages of juicy material. In our best attempt at refinement, we identified a trio of key retro game essentials: Repeating variations of common enemies Linear progression with required boss encounters Key items, scattered throughout, required to win With these three essentials in mind, we began to isolate unique elements of each game to import into the Shadowdark format. We focused on the silly tone of Bart vs the Space Mutants, as well as the helpful NPC encounters and playful items. From Ghostbusters, we echoed the raw simplicity of retro games, with a singular end point at the top of the scary stairs, and added a dash of different ghost enemies throughout. The Mysterious Murasame Castle is a treasure trove of Japanese mythology and combat, so we attempted to compress the game’s five castles into a single five-level dungeon stuffed to the gills with wave upon wave of the choicest enemies.                                 Written by Peter J. Boyle and Jordy Milano Layout and Cartography by Jordy Milano Art by Adam Dvorak Old Game Consulting by Tyler Newcomb Edited by Peter J.

Rumble at Ramlaat Ridge
Rumble at Ramlaat Ridge

Savage Orcs, known as Ramlaat’s Roughnecks, have kidnapped Arcanist Plume and used her expertise to build the Overcastinator, a volatile apparatus designed to smother the world in darkness. The Ridge needs heroes to rescue Plume and shut the device down before the darkness spreads. Designed for the 8-Bit Shadowdark Game Jam, Rumble at Ramlaat Ridge is a point-crawl adventure designed for 3rd-level crawlers inspired by the following NES titles: CLASH AT DEMONHEAD This game puts you into a race to rescue a kidnapped scientist and stop his doomsday bomb. Explore a non-linear, point-crawl world, defeat the Governors, seize their medallions, and shut the weapon down. Its quirky NPCs, game structure and overall vibe were a major inspiration. INDIANA JONES AND THE TEMPLE OF DOOM Endless levels of mine carts and lava were a direct inspiration for the world design. Keen-eyed adventurers may uncover some evidence that this famous archaeologist may have visited Ramlaat’s Ridge. DRAGON WARRIOR III Some of the iconic monsters of Dragon Warrior III can be found prowling Ramlaat’s Ridge. Although introduced in later entries to the series, the Mini-Medal system inspired the Hidden Totem hunt.

Gristle & Vine: Crypt of the Child

This Shadowdark RPG adventure was written for the 8-Bit Shadowdark Game Jam. The Wurm Food Tavern is an unfortunate place. Twice now, part of the tavern has collapsed and patrons were lost. Except this time, the townsfolk are upset. The tavern Keeper Strum is hiring adventurers to go down and figure out what happened the townsfolk that fell into the hole. He warns the groups about vampires & snakes, but prays they can find something about this place before the Count or the townsfolk destroy his livelihood completely. He’s even willing to put himself into financial ruin for your assistance. Does your party have what it takes to brave the depths and enter the Crypt underneath the tavern dedicated to a child vampire?  Intended for mid-level groups of 4 people.  —  While this was written and put together in 2 weeks,  I still hope you’ll give it a try and see if you like it. I want to thank Sleepless Seven for his pixel art portrait assets that are used in this adventure. All other writing and art was done by me. No AI. Made by Idle Hands, Not Ugly Robots. No AI.
