Disappearing Room Glitch

The Disappearing Room Glitch is an extremely rare glitch that can occur at any time.

Description
Although it is extremely rare, the door can sometimes appear blank before the disappearing room glitch occurs.

The next stage may consist of nothing visual, except the balls you throw, Power Ups, some shadows, light (laser coatings and holes in the ceiling (for Falling Glass Planks) in the case of Checkpoint 3 stage 4) and the gradient. The empty coloured stage has collision for stone surfaces, but itself stone is invisible. There is a blank door at the end, which leads to the next room.

The next room may consist of absolutely nothing. The room fails to load entirely. No solid surfaces, no objects, no music, not even the room, and don’t even think about stages. just the endless abyss of echoing after throwing a ball, and a white background.

Zen Mode
This glitch appears to be more common on zen mode, and possibly on only some devices.
