Map

This level is too simple, so I'm not writing a walkthrough for it. This map should get you to finish it though:

To Get Key: Follow these numbers: 1, 2, 3, 4(key)

To Go to Boss: 1, 2, 5(climb vine to top and press to jump and catch hold of second vine), 6, 7, 8, 9, 10, 11, 12(go through door), 13(go through door), 14, 15, 16(go through door to Boss).
After you kill the Boss, you'll see a door. Go through and then enter the door to the Satano town.

Secrets:

• Go left from 1 and fall down the vine. Go left and you will find a chest containing gold.
• Climb down vine at 5, go right until you reach a lift. Move the lift to the top and slash your sword at the deadend top corner. The wall will crumble to reveal a blue potion.
• From 12(in Cavern of Peligro), go left and jump across chasm, climb 2nd vine and go left to the dead-end. Slash your sword at the wall and it will crumble to reveal an Almas C(100 almas)

It's time to go deeper into the Caverns and locate Jashiin.
