Key

Key is one of the elements that occupy the space of level grid, from Items Tab. Keys are Items present in BFDI: Branches levels, which toggles color blocks between On and Off Blocks. They function similarly to Buttons, with only difference being that keys are single use items. Keys can move on Tracks, just like Platforms do.

Keys have 4 variants, for every color each.

Appearance

Every key has the same shape, that seemingly does not belong to any keyhole. Difference between the keys is the color and shape of the handle, which is the same shape as the corresponding block color. Red key has a square, blue key has a triangle, yellow has a circle and green has a diamond (rhombus).
