Mouse Trap (Mechanic)

The Mousetrap is a cut mechanic from F-Stop. It is assumed to be from early development as it can only be seen in early concept art (featuring an early color scheme) next to the door of a test chamber.

As of now, it's unclear what exactly this mechanic was, but it might have been similar to a portable Aerial Faith Plate. It has a snapping sound still left in the game, and the only map it's known to be in is puzzle_chickens (which is also an early map), which indicates it might have interacted with the chicken in some way.
