Glass Panes

In Smash Hit, a Glass Pane is considered any thin sheet of glass that is not too long for its height. The only "glass panes" that don't move or do anything, are seen in More Games.
 * If it is thick but still square/rectangle, consider it a "slab" or a "block".
 * If it is excessively long for its height but still thick, (aspect ratio 1:2.5 or 2.5:1), then it is considered a glass bar.
 * If it is thin but still looks like a glass bar, then consider it a slim glass bar. (exclusive to Checkpoint 1 stage 2/Local Multiplayer)
 * If it is hanged on strings, consider it a string obstacle, a seperate category.
 * If it has other parts (metal, etc), see the next section.

Obstacles using a glass pane within them

 * If it is attached to a metal slider, then if it continuously slides, it is a Sliding Glass Pane, otherwise if it shifts, it is a Shifting glass pane.
 * If it is attached to two spinning metal bars, it is a Spinning glass pane, otherwise if it spins on a metal circle or cylinder it is a Propeller.
 * If a sliding glass pane is excessively tall for its length, then it is considered a Moving Glass Column. (exclusive to Checkpoint 1 stage 1/Local Multiplayer)
 * If it "pops" up or down in one direction only, it is a Pop Up Glass Sheet, otherwise, if it "pops" both ways alternatively, it is called a Pop Up/Down Glass Pane.
