Project Name: Rusty Roguelike

Short Description

A Dungeon crawler with procedurally generated levels, monsters of increasing difficulty, and turn based movement

Story

The hero’s hometown is suffering from a plague of monsters. Welling up from the deep, they seem unstoppable. Legend tells of the Amulet of Yala that can be used to stem the tide. After a long night at the tavern, the hero promises to save the day - and sets forth into the dungeon.
