Yup, this puzzle is complicated it can only be described as awful - no matter how good your dexterity and patience, the Inside3 team have placed dozens of traps and dead-ends to keep you scratching your head for hours. Rest assured, the player is provided with a map and in the worst case scenario, the puzzle can be taken apart to retrieve the ball if it does get lost for hours in the darkness - but that would just be quitting! Made in France to high standards, the ZERO series of puzzles from Inside3 is the ultimate labyrinth challenge.
