Crusher blocks (Colourblind)

Crusher blocks are hazards in Colourblind

Appearance
Crusher blocks appear as big green rectangles of various sizes. They have teeth-like objects on all of their sides, but the bigger ones are on the bottom and the top of the crusher blocks. They have two small eyes in their bottom left and bottom right corner. Like many hazards in Colourblind, crusher blocks can only appear in one color, their colour being green.

Game information
As crusher blocks can only appear in green, the player has to touch a green totem for them to appear. They will move up and down in a set path. They will move in one direction slowly, giving the time for the player to pass by them; but will move in the other direction very fast, being hazardous to the player as they can easily crush the right eye. Crusher blocks often appear in pairs, one being on top of the other to better crush the player in the middle. Although their size may vary, two paired crusher blocks will most often be the same size.
