Checkpoint 11

Checkpoint 11 (a.k.a City or Hell) is the checkpoint before the Endless Mode and after Checkpoint 10.

Description
The checkpoint's theme is reminiscent of hell, and features spinning star-shaped Hammers. The color schemes are red to orange and red violet. The level is added along with Checkpoint 10 in the 1.2.0 update. Before this, Checkpoint 9 was the last checkpoint.

The 4th zone's color is blue for unknown reasons, but red blocks and red glass are still there for part of the background.

1 (a.k.a Trench)
The player will have to face Dual Revolving Hammers, Spinning star-shaped Hammers, Sliding Glass Panes and lasers on moving columns. It is, for some, the hardest zone in the checkpoint. There is a one-button door at the end.

2 (a.k.a Fall)
Stage 2 is featuring more flying glass panes, as in the third stage of Checkpoint 10, but the glass is longer and thicker.

The room rotates slightly. This also happens in Zen Mode and also for the 5th and 9th stage of Versus Mode and Co-Op. (etc.) It ends with a 1-button door.

3 (a.k.a Narrow)
Stage 3 features Sliding Glass Panes and spinning star-shaped Hammers like Stage 1 but with transformational crystals and 2 glass bars moving side to side rapidly in an opposite direction. The stage ends with a 1-button door.

4 (a.k.a City)
Stage 4 has Dual Revolving Hammers and spinning star-shaped Hammers. There are transformational crystals spread out on moving columns. The room rotates when it gets to half of the checkpoint, and leads to the Endless Mode (after the boss on (Mayhem Mode), similar to the 2nd half of the 3rd stage of Checkpoint 9 in a previous version.

Upon finishing this stage, the player passes the Columns and then will see a sign saying that he is "now entering Endless Mode."

The door automatically opens/1 button to end in Mayhem Mode at the end of this stage. In this boss battle, there would be even more transformational crystals.

Trivia

 * Checkpoint 11 goes to the Endless Mode in Version 1.2.0 and later.

Double-Doors Glitch

 * The bosses have transformational crystals and an Automatic Door, although the 1-button door before the boss stage (including the wall) is actually in the boss stage due to the Tunnel to Endless Mode being cut off from the end of Stage 4, and being repositioned at the end of the Boss stage.
 * In other words, the door at the beginning of the boss stage is not exactly at the beginning, and stage 4 won't have a door attached to it, instead using the boss's "entrance" door, as an exit for stage 4. (Though most players won't see the slight time difference).
 * This boss stage is the only one to have 2 doors: 1 partly inwards, and the other in the Tunnel.
 * Apparently, this causes a glitch known as the Double-Doors Glitch.
