| You get an achievement!
This level has one or more achievements. The achievements are listed on the level infobox.
This is level 3 of the Way Back.
This level has an achievement called "Frozen Bridge" requiring you to beat the level, only touching the ice. (The very first tile won't count against you.)
New Tunnel Edit
During this level, you can see two others. Not The Way Back is 5 levels long and is completely optional. Level X cannot be played yet, but you unlock it after beating part 7 of this tunnel. It has only one level. It helps you get to The Way Back, part 8, the reason I won't reveal since that would spoil the plot.
