Climbable Ceiling

Climbable Ceilings are a gimmick that appears in Sonic Boom: Rise of Lyric. They are a type of ceiling that indicate where the player can use Arm Swing.

Description
The Climbable Ceilings are horizontal surfaces covered entirely in deep red and rough-edged crystals on the bottom. Their purpose is to provide ways for Knuckles to traverse the environments in the game's levels using his specific character abilities.

In gameplay, the Climbable Ceilings indicate which and where on ceilings that the player is able to utilize Knuckles' Arm Swing ability to climb across them, meaning that Knuckles is only able to climb on the parts of the ceilings that are covered in red crystals. To use the Climbable Ceilings in gameplay, the player just has to touch them, either by jumping or with a gimmick like a Bounce Pad.

Climbable Ceilings do not necessarily provide safe passages. Some of them have their path block by breakable obstacles and others have spiked balls, which can cause damage upon contact, attached to them which the player must navigate through.
