Version 0.1

This version is the first version to have all checkpoints of Initial Release (Version 1.0.0) (Checkpoint 10 and Checkpoint 11 were introduced in the later version 1.2.0). A download for this version is available for iOS on archive.org. It can be installed by adding the app to the iTunes library and syncing it to an older iPhone (5 or lower).

Differences from Version 0.0

 * Checkpoint 4 stage 3 was set to no rotation; it only rotated on Version 0.0 and connected to Endless Mode.
 * Checkpoint 5 and above were added. They all, (except Endless Mode) didn't exist in Version 0.0.

Differences from later versions

 * Checkpoint 10 and Checkpoint 11 was introduced in Version 1.2.0.
 * The Spiral (Checkpoint 9) at the end had a upside-down door since Version 1.2.0 instead of the tunnel.Game Modes (except Classic Mode) didn't exist until Version 1.3.0 or Version 1.3.4 (depends on the type of phone or tablet or iPad you use).

Differences from Version 0.9.0

 * Version 0.9.0 had a total of 9 checkpoints (including Endless Mode and introductory stage), meaning that Checkpoint 8 and Checkpoint 9 were temporarily scrapped.
 * The Tunnel to Endless Mode was on the last stage of Checkpoint 7
