Start by getting rid of the enemies in the first room. If there are no doors, start searching the walls, you can repeatedly search the walls by typing out 20s. most corpses are safe to eat within 15 turns or so, afterwards they’ll give you food poisoning. A good rule of thumb is whatever your pet eats is safe to eat, but never eat kobold corpses, they give you food poisoning. Let your pet walk over armor to determine whether or not it’s cursed, if it says your pet reluctantly steps over a piece of armor or a weapon, then it’s cursed, use #call to mark it as such if desired. This should get you past at least the first floor of the dungeon. Good luck!
