Nucharacter This level is a major plot point!

This level is a major level in the game. After you finish the level, you may be able to access other characters, minigames, and tunnels. Most of them also include a cutscene.

Introduction Edit

This is level 40 of the Main Tunnel.

Suggested characters: RunnerFront ChildFront

Gameplay Edit

In this level, try to avoid the crumbling tiles, since if one crumbles, lots of them will follow. Make use of changing gravity in midair! If you can avoid all crumbling tiles during this level, you can earn an achievement.

Though it won't count towards the achievement, the Child can beat the level by only moving right.

Note that there is a walkthrough video in the following sections, and keep in mind that this level is done while achieving the Achievement featured in the level.

Achievement Edit

There is an achievement that takes place at this level.

The Conscientious Lizard Edit

In this achievement, you have to pass this level without dislodging any crumbling tiles. (Also, using the Child doesn't count) Note you have to use the Lizard because when you use another character it doesn't work. I tried it already and the video has it too.

There is a walkthrough of this achievement back in the Gameplay section.

There is a cutscene featuring in this level. More can be seen here.

Heavy Sleeper Edit

The Skater finishes Level 40, and runs into the sleeping Lizard. He says he is sorry for bumping into the Lizard and he was caught off guard when the gravity changed, but then he realizes the Lizard is sleeping and carries on. The next slide is a "Choose your character". Clicking the Skater will play Level 41 . Clicking the Lizard pans the camera into the stars. What follows is a black screen. After a while, the Lizard wakes up and goes into the B-Tunnel.

New Character Edit

After playing this level, you successfully unlocked the Lizard!

This level is the second level that gives you a character (Level 10 you get the Skater)

Here are some data about this character:

The Lizard has the highest jump. Its biggest weakness is the fact that if it jumps, it jumps high. This means it struggles in areas with close platforms, where small jumps are better. Its speed is 9 m/s.

If the Lizard fails a level many times in a row, it gives up and goes to sleep. Until it wakes up, players have to use other characters. It used to sleep for an hour, but the time was shortened to 10 minutes for obvious reasons. The Lizard can be woken up sooner by repeatedly clicking on it in the menu screen or the pause screen, however, it will still be sleepy and fall asleep much sooner. When the Lizard falls asleep, a one-frame cutscene will occur, mostly with the Child.
