Introduction[]
This is Level 4 of the Low-Power Tunnel in Run 3.
Suggested Characters: 
Gameplay[]
In this level, you actually don't need to jump to beat this level as the platform is continuous (though, you can still jump just to make sure.) There are unlit Power tiles between all platforms, so what you need to do is walk, run or skate. The level is overall quite simple, and shouldn't take too many attempts once you know the pattern.
Use the Runner to have an easier time beating the level or use the Skater if you want to pass the level in a fast and quick manner.
Side Tunnel[]
Branching off this tunnel is a bunch of tiles floating in space, which is later transformed by the Gentleman into the Memory Evaluation! But you have to pass the Bridge Building and Angel Missions first, which is quite a long way down the track from here.
This Gentleman-exclusive tunnel is seven levels long, there are also gates that separate each level, which is very different from other tunnels. The gates are each three tiles long and circle the width of the tunnel, and there is one unlit tile in the center of each side of the gate. After the initial gate, there is a series of platforms arranged in a specific pattern, then another identical gate. Following the second gate, there is another set of platforms in the same pattern, however, they are mostly, if not all unlit, requiring the player to somewhat memorize the pattern from before.
