An Island Adventure

You march off to the left, ignoring the cave, and follow the course of the hill
It is far too rough and dangerous to climb up the hill and so you keep walking.
After several minutes of walking you come, as expected, to the edge of the island. The hill is acting as a natural barrier and you guess that beyond it is simply more ocean.
You turn on your heels and head back, passing your fellow survivors, as you follow the perimeter in the other direction just to confirm your suspicions.
It only takes you a few minutes to, once again, come to the island's edge. Rocks and ocean greet your frustrated glances.

Sighing, you head back to where your fellow survivors await...
