The Crescent

The Crescent is a crescent moon in Jetshift that serves its purpose as a time limit. It starts in the west at a rotation of -70 degrees. It continuously rotates very slowly towards the east of the level, where it will set and stop rotating.

If the player takes too long to pass a level where it appears, such as boss battles or side-scrolling levels, a warning will be issued, telling the player to 'hurry up'. If they still take too long to complete the level, The Crescent will set and the level will terminate immediately. (roughly 10 minutes, or 19,200 frames at 30 FPS).Due to how the game works, some timers might appear to last longer on slow computers (for example a person with a very slow computer can make the level last longer), but does not affect the number of frames that The Crescent has until it sets. This makes it possible to complete a level in the course of over an hour, depending on the speed the game is running at.

During a Lunar Eclipse, The Crescent will appear orange and will not speed up or slow down.

The Crescent will also not appear after Level 80, allowing for infinite time during the levels in Hell Valley.

History
Originally, after The Crescent sets, the player would take slight damage over-time until they die. This was scrapped because the player could die during the results screen, resulting in a completion and failure at the same time.
