This level serves the role of introducing the darkness to the players, so they won't freak out when they discover the threatening darkness in the later levels. This is level 1 of this tunnel, so good luck.
This level serves as an introductory level of the power tiles. Since this is the first level that involves this special feature, it won't be too hard.
Most of the time at this level you can see the tiles easily, but they may suddenly blink and may become really dark when approaching the end of the level, so be really careful.
Most of the time the level is almost as easy as Levels 1 to 4. But because the level consists of 'little' darkness afterward, it barely reaches the "Not too easy" difficulty.
There is an Achievement in this level.
