Checkpoint 9

Checkpoint 9 (aka Geometry, internally named Phosphor) is the tenth and ninth official checkpoint in Smash Hit.

It was originally the final checkpoint before endless mode, before Checkpoint 10 and 11 were added. The game would lead you through a spiral to a tunnel after completing the checkpoint, and you'd enter endless mode. In Version 1.2.0, the tunnel was moved to the end of Checkpoint 11's columns.

Description
The theme focuses on geometry, with color schemes of green to light yellow. It also introduces the Hollow Glass Cubes, as well as five-bladed propellers.

1 (a.k.a Cube City)
In the beginning of this stage, there will be two Infinite Balls Power Ups. There will just be Hollow Glass Cubes. (37 in Training Mode).

Inside them you will find either another smaller cube, or an Octahedral Crystal inside. Some Octahedral Crystals are also scattered throughout the stage, appearing on pedestals. There are 2 Star Shaped Crystals at the end of this stage.

2 (a.k.a Castle)
At the beginning of Stage 2, you will find an "Explosive Ball" power up. The room will then start to rotate a few seconds later, and the player will shoot differently shaped propellers with up to 5 blades. 2 star shaped crystals are at the end of this stage. The door has 2 buttons.

3 (a.k.a. Geometric Forest)
From the beginning of the zone until the very end of the level, there are forks and many glass bars. During the middle of the level, a brief intermission will occur, with 2 hollow cubes containing 2 star shaped crystals. Subsequently, the level will continue. The obstacles are the same for the next part, but the room rotates halfway through, and the music is slightly different.

At the end, the music fades. Following is a spiral leading to an upside-down door, going to Checkpoint 10 (door) or Endless Mode (tunnel, before Version 1.2.0). In Mayhem Mode, this will lead to the Boss.
