| 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.
Notice: The Angel will be the only recommended character.
You have to play this level backward and with no Crumbling tiles. This is pretty difficult, as you can see, there are huge gaps in it. The best way to clear these jumps is to maximize air distance, consisting of a long jump and a dash. You should be able to make out to most of the platforms with this. If you cannot, try to stick onto the platforms on the wall. The Angel doesn't have a very good max height, and won't land jumps perpendicular to his wall, since this is a physically big/wide tunnel.
There is a cutscene that featured in this level. More information on this cutscene can be found here.
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 there are many interesting things to discover in space. Angel questions him by asking what she could discover in space. The Student then says there are many scientific discoveries that can be done. Then, the Angel says that he discovered the yellow rings seven and a half months before Student and Runner. Then, the Student says it is not enough to stick a ring on their head and need to understand the science about the rings and they can build one from scratch. Then she insists that she and Runner can research the rings better than the actual scientist can.
After the completion of the Angel Missions, a new tunnel will be unlocked, and this is The Way Back! It has 16 levels and leads to 4 other tunnels. More about this special tunnel can be seen here. To learn about the levels of The Way Back, go here.
