In this challenge there are only indestructible barriers, the player has to avoid obstacles from the barriers that will come from above something like the weakest link.
Over time, the barriers come faster and faster, and there are more of them!
(The width of the vertical barriers may also decrease)
The player has only 1 life and plays until death, the longer you survive, the better place you will be.
The mechanics of the Barrier Switches and Spectral Barriers can also be used.
