Spiral (Checkpoint 9)

The Spiral is a location exclusively seen in Checkpoint 9. It was followed by the Tunnel to Endless Mode prior to version 1.2.0 and was then followed by Checkpoint 10 in Version 1.2.0. Being a decorative wall-type structure, it is made of stone.

Appearance
It has a wide wall, and the subsequent walls will then join at right angles to the previous walls, getting closer together until they reach the tunnel (versions 1.0.0 to 1.1.0) or door (version 1.2.0 and later). The music will fade when the spiral is near, and it will then change to short, frequent beats.

When you enter the tunnel (pre-1.2.0 only), "now entering Endless Mode" will show up.
