Sometimes you need to take two steps back in order to move forward
You need to navigate towards the goal, and get around the Walls in your path. You can use explorer.getSpace().isWall() to see if the Space to the right is a Wall. You can also pass a Direction parameter to getSpace to check another Direction, such as:
explorer.getSpace(Direction.DOWN).isWall()
Challenge
Navigate around the walls and reach the goal!

Jun 24, 1:58 PM@Andreas, sorry, that was caused by an error when Explorer attempts to make 2 moves in 1 turn. Remove your double move attempt and you'll be fine.
