is a remove-type property. If something is , the object flies off into the air and is removed.
If 
is formed, a secret ending is played.
only plays the ending in the main game. In custom levels, it WINs the level and gives a special stamp. In levelpacks, it also boots you back to the main menu.
- The specific trigger to have this occur is to have an all is done rule, even if inactive due to a condition, and to done at least as many objects as there are total objects in the level (only counting the ones that are in all). For this purpose, done stacks.
- Forming in the main game also causes to be DONE as well. In custom levels and levelpacks, however, the rule behaves like every other rules and text remains on the screen.
- Forming with conditions (e.g. ) will trigger the DONE ending in the main game if every object on the level fulfills said condition (e.g. every object is NEAR a ). In custom levels and levelpacks, this WINs the level.
- without any in the does not count as making .
- after doesn't bring back, but it still prevents future s from being doned.
- is unaffected by and does not trigger , as it doesn't actually destroy an object.
- has the visual effect of every object in the level flying up as if it was , but actually behaves as expected (essentially destroying the level).
- interacts in few unexpected ways with :
- If all objects that were are , game switches back to 2D perspective. This differes from other ways of destroying object (e.g. or ), which leave first-person view active.
- 's destruction effect plays relative to the screen, making it appear above everything in 3D view and rotate with perspective.
- If all objects that were

Appears in Levels:[]
Trivia[]
- In past versions of the game, was strange in the order of operations, in which objects were tagged as being done and then only later actually removed. This caused lua errors to interrupt an undo midway through.
- In builds 29 to 36, would instead just spin the object around instead of flying up.
