Difficulty: ★★

Code for plan() spell is here:

# Each coin has a gold value associated with it, but we don't know how much.

# Let's say I want to collect gold with total value 20.
# Here we use while loop, as we don't know how long the loop will run.
@moveRight()  while @gold < 40

# Now collect coins worth 40.
# If you want to kill the ogre, be careful as you will need atleast 70 health.
# Note: Mushrooms will decrease your health, which might even kill you.
# Write the while loop smartly.
# Your code here.
@moveUp()
@moveUp()
@moveLeft()
@moveLeft()
@attackNearbyEnemy()

#@moveRight()  while @health < 80
