The Pit

After going through the Tunnel with cleft, you face a closed door.

Behind it is a pit, so you should kick the door open then climb into the pit and not charge through it (and fall).

The cave to the left contains some Giant Aardwolf meat you can pick up.

The cave to the right contains slime monsters who will attack you if you survey their lair.

Whether you peruse the caves or not, you'll end up with no choice besides going back to the first fork.
