Treadstone is a sort of Roguelike game, sort of like Slender Man. That's much of the story already; but wait, there's more! You find yourself in a vast, absolutely black, dark dungeon, of infinite dimensions, carrying only a flashlight to illuminate your way, and you are tasked with finding eight, variously colored gems. Find them all, before The Beast gets you, and you win. It's a walk in the park, except that it's dark! Play it now in your browser. On a console computer, use arrow keys to move, mouse to point flashlight. On mobile use touch.
