Author's blurb:
DELVE: A Solo Map Drawing Game is a map drawing game that puts you in control of a dwarven hold as you discover the horrors that lurk below. This zine has everything you need to generate natural formations, forgotten ruins, enemies, wyrd magics, and ancient monstrosities. It has a simple turn-based combat system, rules for building your hold and optional challenges for a harder experience.
Inspired by games like Dwarf Fortress and Dungeon Keeper, DELVE aims to capture that feeling of building and protecting a fortress in an unforgiving subterranean world.
All you need to play is, a pencil, paper (preferably 1" grid), and a deck of playing cards.
