The U-Tunnel is a side tunnel that branches off of Level 40 of the Main Tunnel, along with the B-Tunnel. The tunnel consists of ten levels which can be played with every character. It is not visible until you play 50 levels, and then if you click on the planet (which is now yellow) a cutscene will ensue. Afterwards, the U-tunnel will be available to play.

Suggested Characters: U-Tunnel (1)U-Tunnel (2)U-Tunnel (3)


The 10 levels of the tunnel proves that the side tunnel is quite a long one, compared to most other tunnels.

The levels aren't too hard, though some may be a little bit harder, and some will be quite hard. The average difficulty is over medium.


There are six cutscenes in this tunnel. More information can be found on the Story page.


After beatingLevel U-10, a cutscene starring theDuplicatorand theRunnerwill begin. The Duplicator whispers to the Runner asking where she put thePlanet, and that he promises not to tell anyone. The Runner looks exasperated as she explains once again that she didn't steal it. She then leaves to map out another tunnel and tells the Duplicator to "Catch up once you realize that the Planet orbits faster than us."


The Student meets the Gentleman, and Gentleman asks her if she arrived at a solution to his affliction. The Student tells him about the rings she found on the boxes, but the Gentleman doesn't accept her answers, nor doing a test with her, as he thinks this is not valuable. The conversation ends by the Student saying that she doesn't know what the Gentleman expects her to do.


The Angel and the Student meet during the Angel Mission (The Nerd). Angel tells the Student to go home with him, but the Student says refuses, saying that she has scientific discoveries to make. Angel asks what she could possibly discover in space and she lists some. Then, the Angel says that they just discovered the yellow rings and the Student responds that there is science behind the rings that he must understand. Then she insists that she and Runner can research the rings better than the actual scientist can.

Planet Stolen[]

Upon clicking onU-10, a cutscene will begin showing a discussion between theDuplicatorand theRunnerabout the strange disappearance of thePlanet. The Duplicator tells the Runner that the Planet is gone, but she only says "It'll come back." Then the Duplicator accuses the Runner of being the one who stole the planet, to which the Runner responds, "I think I'll ignore that entirely," and the two proceed to map out the next tunnel.


After reaching the backwardsLevel U-8box push during the Bridge Building, when someone presses the home button, this cutscene will be initiated. The Student complains about she is frustrated to push the box all over the tunnel every time she falls out the tunnel. The Runner then tells her that if she teleports while being very calm, the box won't move.

Student Teacher[]

When the Power Cell doodle is clicked on the map, a cutscene will begin inLevel U-2in which theGentlemanseeks advice from theStudent. He explains that the power cells pull him toward them instead of vice-versa and asks if he might have installed the electromagnet in backwards. The Student runs an experiment and throws a power cell in the air. The Gentleman flies toward it and off the screen, but then reappears and shouts at the Student. She apologizes. He eventually agrees that they learned that electromagnets work in all directions.


There is 1 achievement in this tunnel.
