If I was not aware of what kind of magic James can do in level designing, I would never believe this game has been made in such a short amount of time!
You will not enjoy one but 4 differents levels, rich, dense, but never too wide. You will have to find your way but you will never get lost. As usual with James, this is a real lesson of level design, which is at the center of the game mechanics and the artistic direction.
Well done!
