Checkpoint 9

Checkpoint 9 (aka Geometry, internally referred to as Phosphor) is the tenth and ninth official checkpoint in Smash Hit. It came before the Endless Mode in Version 1.0.0.

Description
The theme focuses on geometry, with color schemes of green to light yellow. It also introduces the Hollow Glass Cubes.

Before Version 1.2.0, Checkpoint 9 was the last level, also joining Endless Mode.

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 you will shoot differently shaped propellers. There are 25 screen propellers (type-S), and 23 or 57 propellers in total (see the table below, which is correct? I de-cluttered the headings.). 2 star shaped crystals are at the end of this stage.

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. In the middle of the zone, there are 2 big Hollow Glass Cubes with 2 crystal stars. 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, only in versions 1.0.0 or 1.1.0). In Mayhem Mode, this will lead to the Boss.

Trivia

 * This is one of five checkpoints used in the press kit.
 * The second stage, and its music, is used in the trailer.
 * Checkpoint 9 ends with a spiral.
 * The door button is upside down in the end of Stage 3.
 * The door with the button being upside down is COMPLETELY harmless.
 * Checkpoint 9 is the only known checkpoint with a door that doesn't crash.
 * This door used to be just a blank outline to the tunnel. Now, this tunnel has moved to the end of Checkpoint 11.
 * A LEGO version of the checkpoint has been built.
 * This is the only checkpoint with a Power Up in the Boss stage, specifically, Infinite Balls.

Version 1.0.0 (Initial Release)

 * Apparently, there was no door prior to version 1.2.0 at the end of Stage 3, prior to that version, it would lead, through a tunnel, to Endless mode.
 * Checkpoint 9 was originally the last level before Endless Mode in the versions at V1.0.0 and V1.1.0 of Smash Hit before 1.2.0, which two levels, 10 and 11 were added, and then the Boss (with Infinite Balls Power Up) in V1.3.4.

Significance in Marketing

 * Checkpoint 9 is featured in Smash Hit - Official Trailer and even uses the music.
 * Many obstacles found in other Game Modes and checkpoints are shared with Checkpoint 9.
