Downland

You found an opening into what looks like an underground cavern!
You enter the cave, and suddenly a rock slide cuts off your exit.
There's no turning back. You have no choice but to continue
through the cavern, looking for another exit.
As you explore the cave, you realize that others have been here
before. Ropes are hanging from ledges throughout the cave, and
treasures, such as diamonds and bags of gold, are scattered
everywhere. Suddenly you come upon a key. The key must be
magical for when you pick it up, a door appears. You must get to
that door! Surely, it will lead you to safety.
Collect the treasures and keys, and make your way to the door by
climbing the ropes and jumping onto the ledges. But be careful! It
will take all your skill to keep from falling or being hit by acid drops
or boulders. Also, beware of the poisonous bat that is waiting to
destroy you!
