Checkpoint 6

Checkpoint 6 (aka Pink Cave or Cave2) is the checkpoint after Checkpoint 5, and before Checkpoint 7.

Description
The checkpoint's color scheme focuses in either maroon or dark cerise. Checkpoint 6 introduces no new features, but variations of previous obstacles, such as smaller spinning glass panes. It is also extremely fast. The difficulty on this checkpoint for first-timers could be significantly massive.

Stage 1 (a.k.a Pink Canyon 1)
The player will be faced with faster-moving spinning glass panes. These are similar to the ones in Checkpoint 3, but faster and thinner. The crystals are: 1 or 2 Octahedral Crystals on Moving Columns and 2 Pyramidal Crystals on the ceiling. Its music is also the bosses' main theme, and is repeated as well in Endless Mode stage 1 and 4, Zen Mode, and Smash Hit - Official Trailer.

Stage 2 (a.k.a Pink Cave and Narrow)
Stage 2 has 2 parts.

Part 1
Part 1 introduces more spinning propellers (some vertical ones as well) and lasers. And this zone doesn't have a door when the music ends (it goes to Part 2). Its music is also the bosses' intro (also repeated in Zen Mode.)

Part 2
Part 2 has many Square on Strings and some more propellers. This stage is featured in Smash Hit - Official Trailer.

Stage 3 (a.k.a Pink Canyon 2)
This stage may be difficult. It has similar obstacles from the 1st stage, and there is a 1-button door to end, going to Checkpoint 7 (the boss in Mayhem Mode), with 2 octahedral crystals on one of many, crystal stands.

This stage looks very similar to the first stage, but slower, with inverted gradient background and different music.
