Gruesome is a coffee-break rogue-like where you play a grue. This is a reference to the grue in Zork, a monster that eats adventurers who stray into the dark. Both you, the grue, and your prey, the adventurers, have a single hit point. If they stumble into you, they die. Their light, on the other hand, is deadly to you. This results in antics where you run circles around the adventurers avoiding their lights and hoping they will walk backwards into your slavering fangs.
Gruesome is a short game and it cannot save the game.
